Description

Coated article, method of making coated article, and method of making composition
Technical Field
The present application claims priority from U.S. c. ≡119 U.S. provisional application No. 63/299052 filed on 1 month 13 of 2022, U.S. provisional application No. 63/277625 filed on 11 month 10 of 2021, and U.S. provisional application No. 63/172250 filed on 8 of 2021, the contents of each of which are hereby incorporated by reference in their entireties.
The present disclosure relates generally to coated articles, methods of making coated articles, and methods of making compositions, and more particularly, to coated articles and methods of making coated articles including pen hardness, and methods of making compositions comprising a plurality of functionalized oligomeric silsesquioxanes.
Background
Foldable substrates are commonly used in, for example, display applications such as liquid crystal displays (liquid crystal display; LCD), electrophoretic displays (EPD), organic light emitting diode displays (OLED), plasma displays (plasma display panel; PDP), and the like.
It is known to provide a coating comprising an organic material on portions of a foldable display and/or a foldable protective cover. For example, such organic materials may provide antimicrobial, easy to clean, and/or hydrophilic functionality. However, organic coatings can have durability issues, such as being susceptible to abrasion and/or hardness.
It is desirable to develop a foldable display and a foldable protective cover for mounting on the foldable display. The foldable display and the foldable cover should have good impact resistance and puncture resistance. At the same time, the foldable display and the foldable cover should have a small minimum bend radius (e.g., about 10 millimeters (mm) or less).
Accordingly, there is a need to develop coatings for display devices and/or foldable devices that have high transparency, low haze, lower minimum bend radius, and good impact and puncture resistance, as well as coated articles including coatings and substrates (e.g., glass-based substrates, ceramic-based substrates).
Disclosure of Invention
Described herein are compositions, coatings, and coated articles comprising a variety of functionalized oligomeric silsesquioxanes, and methods of making such compositions, coatings, and coated articles. The coated article may be used as a foldable substrate and the coating and/or coated article may be incorporated into a foldable display. A variety of functionalized oligomeric silsesquioxanes can provide good scratch resistance and/or high pen hardness (e.g., about 5H or greater, about 7H or greater, about 9H or greater). The provided plurality of functionalized oligomeric silsesquioxanes can react with the first functional group and/or the second functional group of the linking group (e.g., polymer). The degree of functionalization of the plurality of functionalized oligomeric silsesquioxanes may facilitate the binding of the polymer to two different ones of the plurality of functionalized oligomeric silsesquioxanes. Providing the coating on the substrate improves the durability of the coated article, for example by filling surface defects in the substrate and/or protecting the surface defects in the substrate from damage. In addition, the substrate may include a glass-based substrate and/or a ceramic-based substrate to enhance puncture resistance and/or impact resistance. In addition, the glass-based substrate and/or ceramic-based substrate may be chemically strengthened to further enhance the impact and/or puncture resistance of the coated article while promoting good bending properties.
The composition may comprise a linking group (e.g., a polymer) having functional groups at opposite ends of the polymer, wherein the functional groups react with the functionalized oligomeric silsesquioxane. The linking group may include a polymer that may reduce (e.g., prevent) aggregation of various functionalized oligomeric silsesquioxanes, may provide good optical properties (e.g., high transmittance, low haze), and as a coating, may provide good durability and/or good adhesion to the substrate. Providing a linking group (e.g., a polymer) that includes oxygen atoms in the backbone of the linking group can increase the flexibility of the linking group, the resulting composition, and the resulting coating, which can increase the ultimate elongation, durability, and/or impact resistance (e.g., pen drop height). Providing a linking group comprising a polymer having a number average molecular weight in the range of about 400 daltons to about 30,000 daltons can prevent aggregation of the functionalized oligomeric silsesquioxane attached thereto while reducing entanglement of the polymer, which can inhibit manufacturability of the resulting coating and/or coated article. Providing a low molar ratio of linking groups (e.g., polymer) to the various functionalized oligomeric silsesquioxanes (e.g., about 0.06 or less) can result in a polymer that binds to both functionalized oligomeric silsesquioxanes, which can achieve the benefits described above. Providing a polymer having a glass transition temperature outside the operating range of the coated article (e.g., outside the operating range of about-20 ℃ to about 60 ℃) may result in a coated article having consistent properties over the operating range. Providing a reactive diluent (e.g., a linking group that is not bonded to the functionalized oligomeric silsesquioxane prior to curing after the composition is disposed on a substrate) can be used to adjust the viscosity of the composition, which can facilitate uniform application and/or enable lower cost application techniques while reducing the overall cost of the composition and/or coating.
Providing a linking group comprising one or more amine and/or anhydride functional groups can provide a coating that has good adhesion to a substrate (e.g., about 4B or greater when formed, about 4B or greater after 10 days in a 50% relative humidity, 25 ℃ environment, and/or about 4B or greater after 10 days in a 95% relative humidity, 65 ℃ environment), whether or not a silane coupling agent is used. Providing a curing catalyst may increase the hardness of the resulting coating. Providing a composition comprising trimethylol propane oxetane can increase the hardness of the resulting coating. The coating may be hydrophobic, have a low dynamic coefficient of friction (i.e., about 0.8 or less, such as about 0.5 or less), good abrasion resistance, and/or function as an Easy To Clean (ETC) coating.
Forming the layer from a substantially solvent-free composition may increase its cure rate, which may reduce processing time. Furthermore, solvent-free compositions may reduce (e.g., reduce, eliminate) the use of rheology modifiers and increase composition uniformity, which may increase the optical clarity (e.g., transmittance) of the resulting coating. Providing a coating process that includes a solvent may enable a wide variety of compositions to be used to form a coating. In addition, the layer is cured by irradiating the layer for a short time to form a coating layer, which can improve the processing efficiency and reduce the manufacturing cost. Furthermore, the solvent-free composition may reduce the incidence of visual defects (e.g., bubbles generated by volatile gases upon evaporation of any solvent) in the resulting coating. Providing the composition with additional functionalized oligomeric silsesquioxane to form the layer may further increase the hardness of the resulting coating and/or coated article. Providing a composition that does not contain a photoinitiator (e.g., a thermosetting composition) may not present yellowing problems. Providing a silane coupling agent can increase the adhesion of the coating to a substrate (e.g., glass-based substrate, polymer-based substrate). In addition, the coating may include high light transmittance (e.g., about 90% or greater), low haze (e.g., about 0.5% or less), and/or low yellowing index (e.g., about 0.6 or less). Providing a composition that is substantially free and/or free of nanoparticles (e.g., silica nanoparticles, alumina nanoparticles) may reduce handling problems (e.g., agglomeration, aggregation, phase separation) of the composition, improve optical properties (e.g., maintain low haze and/or high transmittance even after aging at elevated temperatures and/or humidity) of the coating and/or resulting coating and/or coated article, and reduce mechanical properties (e.g., hardness, modulus, strain) of the resulting coating and/or coated article, as compared to a corresponding composition, coating and/or coated article that includes a plurality of functionalized oligomeric silsesquioxanes without nanoparticles (e.g., silica nanoparticles, alumina nanoparticles).

However, it should be understood that the compositions, coatings, and/or coated articles are not limited to such applications and may be used in other applications. Unless otherwise indicated, discussion of features of aspects of a composition, coating, or coated article applies equally to corresponding features of any aspect of the present disclosure. For example, the same part numbers throughout the disclosure may indicate that, in some aspects, the identified features are identical to each other and that discussion of the identified features of one aspect may apply equally to the identified features of any other aspect of the disclosure unless otherwise indicated.
Aspects of the present disclosure may include compositions. The composition may include a variety of functionalized oligomeric silsesquioxanes. As used herein, functionalized oligomeric silsesquioxanes are meant to include at least two species represented as RSiO 1.5 There are three oxygen atoms in which the other monomer to which it is bound shares each oxygen atom, and R is a functional group that "functionalizes" the oligomeric silsesquioxane to form a functionalized oligomeric silsesquioxane, although R of one monomer need not be the same as R of the other monomer. In aspects, RSiO in functionalized oligomeric silsesquioxanes 1.5 The number of monomers may be an integer of 4 or more, 6 or more, 8 or more, 50 or less, 30 or less, 20 or less, 16 or less, about 12 or less, or 10 or less. In aspects, RSiO in functionalized oligomeric silsesquioxanes 1.5 The number of monomers may be an integer in the range of 4 to 50, 4 to 30, 4 to 20, 6 to 16, 6 to 12, 8 to 10, or any range or subrange therebetween. For example, the leftmost compounds of FIGS. 8-10 show functionalized oligomeric silsesquioxanesExamples are shown.
In aspects, in addition to RSiO discussed above 1.5 The functionalized oligomeric silsesquioxane may further include any number of RSiO in addition to monomer units 2 Monomers, where R may also be at RSiO 2 Monomers and RSiO 1.5 One or both of the monomers may vary.

In other aspects, RSiO 2 The monomer may be bonded to two other monomers. For example, RSiO 2 Monomers can be bound to another RSiO 2 And RSiO 1.5 Monomers or two RSiO 1.5 And (3) a monomer. For simplicity, "non-terminal RSiO 2 Monomer "may refer to RSiO 3 、RSiO 2 、R 2 SiO 3 Or R is 2 SiO 2 Wherein a single "non-terminal RSiO 2 "first R of monomers may be the same single" non-terminal RSiO 2 The other (e.g., one, all) R of the monomers "are the same or different. In other aspects, RSiO 2 The number of monomers may be less than or equal to RSiO 1.5 Number of monomers. For example, when RSiO 2 The number of monomers was 4 and RSiO 1.5 When the number of monomers is 4 or greater, a ladder-functional oligomeric silsesquioxane may be formed wherein RSiO 1.5 Each of the monomers is combined with two other rsios 1.5 Monomer and RSiO 1.5 Monomers or an RSiO 2 And (3) monomer connection. In even other aspects, the leftmost compound of fig. 8 may include a ladder-functionalized oligomeric silsesquioxane, e.g., when block 803 has Si atoms bound to R groups and Si atoms bound to non-terminal endsRSiO 2 R2 radical of a monomer, RSiO 1.5 The R3 group of the monomer, and block 803 includes three or more additional rsios that may be terminal or non-terminal 1.5 Monomer and two other RSiO 2 And (3) monomer.

For example, an open cage functionalized oligomeric silsesquioxane may include an adjacent pair of rsios connected to each other by two or more non-overlapping pathways 1.5 Monomers, and the first path is connected to the second path without passing through an adjacent pair of monomers, while the silsesquioxane further includes 1 to 3 RSiO' s 2 And (3) a monomer. In even other aspects, the leftmost compound of fig. 8 may include an open-cage functionalized oligomeric silsesquioxane, e.g., when block 803 brings one or more of the illustrated Si atoms into RSiO 1.5 Monomers such that RSiO 2 The total number of monomers is 1 to 3, and adjacent pair of RSiO 1.5 The cells are connected to each other by two or more non-overlapping paths, and the first path is connected to the second path without passing through an adjacent pair of cells.

For example, from 8 RSiO 1.5 The functionalized oligomeric silsesquioxanes of monomer composition are octahedral functionalized POSS (e.g., polyoctahedral silsesquioxanes). As shown in fig. 9-10, the leftmost compound is a functionalized POSS, i.e., an octahedral functionalized POSS.

The composition may comprise a first functionalized oligomeric silsesquioxane bound to a second functionalized oligomeric silsesquioxane through a linking group (e.g., a polymer) that is terminated with a first functional group at a first end of the linking group and a second functional group at a second end of the linking group.

Providing a low molar ratio of polymer to the plurality of functionalized oligomeric silsesquioxanes (e.g., about 0.06 or less) may result in a polymer that binds to both functionalized oligomeric silsesquioxanes, which may achieve the benefits described herein. The degree of functionalization of the plurality of functionalized oligomeric silsesquioxanes may facilitate the binding of the polymer to two different functionalized oligomeric silsesquioxanes of the plurality of functionalized oligomeric silsesquioxanes.

Providing a linking group within one or more of the above-mentioned ranges may reduce the overall cost of producing the coated article, for example by reducing the amount of the various functionalized oligomeric silsesquioxanes used.
In aspects, the linking group can include a reactive diluent. As used herein, a reactive diluent in a composition is a substance that reduces the viscosity of the composition and that can react with another substance in the composition. Reactive diluents are in contrast to solvents, which do not react with another substance in the composition. In aspects, the composition may further comprise a reactive diluent. The reactive diluent may include a third functional group at a first end and a fourth functional group at a second end opposite the first end.

In aspects, the substrate 103 or 203, the first portion 321, and/or the second portion 331 may comprise a glass-based substrate and/or a ceramic-based substrate, wherein one or more portions of the substrate may comprise a compressive stress region. In aspects, the compressive stress region may be created by chemically strengthening the substrate. Chemical strengthening may include ion exchange processes in which ions in the surface layer are replaced by or exchanged with larger ions having the same valence or oxidation state. The method of chemical strengthening will be discussed later. Without wishing to be bound by theory, chemically strengthened substrates may achieve a smaller (e.g., less than about 10mm or less) bend radius because compressive stress from chemical strengthening may counteract bending-induced tensile stress on the outermost surface of the substrate (e.g., first major surface 105 in fig. 5 and 7, first major surface 205 in fig. 6). The compressive stress region may extend into a portion of the substrate to a depth, referred to as the compression depth. As used herein, compressive depth means the depth at which the stress in the chemically strengthened substrate described herein changes from compressive to tensile stress. The depth of compression can be measured by a surface stress meter or a scattered light polarizer (SCALP, where the values reported herein are measured by SCALP-5 manufactured by glastress co., estonia), depending on the ion exchange treatment and the thickness of the article being measured. In the case where stress in the substrate is generated by exchanging potassium ions into the substrate, a surface stress meter such as FSM-6000 (Orihara Industrial co., ltd. (Japan)) is used to measure the compression depth. Unless otherwise indicated, compressive stress (including surface CS) is measured by a surface stress meter (FSM) using commercially available instruments (e.g., FSM-6000 manufactured by Orihara). The surface stress measurement depends on an accurate measurement of the stress optical coefficient (stress optical coefficient; SOC), which is related to the birefringence of the glass. Unless otherwise indicated, SOC is measured according to procedure C (glass disk method) described in ASTM Standard C770-16, entitled "Standard Test Method for Measurement of Glass Stress-Optical Coefficient," the contents of which are incorporated herein by reference in its entirety. In case the stress is generated by exchanging sodium ions into the substrate and the measured article is thicker than 75 μm, the compressive depth and the Central Tension (CT) are measured using the SCALP. In the case where the stress in the substrate is created by exchanging potassium and sodium ions into the glass and the measured article is thicker than 75 μm, the compression depth and CT are measured by SCALP. Without wishing to be bound by theory, the exchange depth of sodium ions may indicate the compression depth, while the exchange depth of potassium ions may indicate the magnitude of the compressive stress (but not the change in stress from compression to tension). The refractive near-field (RNF; RNF method is described in U.S. patent No. 8,854,623, entitled "Systems and methods for measuring a profile characteristic of a glass sample," which is incorporated herein by reference in its entirety), methods can also be used to derive a graphical representation of stress profiles. When the RNF method is used to derive a graphical representation of the stress profile, the maximum center tension value provided by the SCALP is used in the RNF method. The graphical representation of the stress profile derived by RNF is force balanced and calibrated to the maximum center tension value provided by the SCALP measurement. As used herein, "depth of layer" (DOL) means the depth to which ions (e.g., sodium, potassium) are exchanged to the substrate. Throughout this disclosure, when the central tension is not directly measurable by the SCALP (e.g., when the measured article is thinner than 75 μm), the maximum central tension may be approximately the product of the maximum compressive stress and the compressive depth divided by the difference between the substrate thickness and twice the compressive depth, where the compressive stress and the compressive depth are measured by the FSM.

CIE D65 illuminant is used as a light source for illuminating coatings and/or coated articles. Unless otherwise indicated, haze is measured in a direction perpendicular to the angle of incidence of light on the surface of the sample (e.g., the third major surface 115 of the coating 113, the first major surface 105 of the substrate 103, and/or the second major surface 107 of the substrate 203).

Without wishing to be bound by theory, the refractive index of a material may be determined using a ratio of a sine of a first angle to a sine of a second angle, wherein light of a first wavelength is incident from air onto the surface of the material at the first angle and refracted at the surface of the material to propagate light in the material at the second angle. Both the first angle and the second angle are measured in a direction perpendicular to the surface of the material.

In aspects, the coating 113 and/or the coated article 101, 201, 301, 401, 601, and/or 701 can include a color shift, for example, as measured by a yellowing index. As used herein, the yellowing index is measured at a 10 ° observer angle according to ASTM D1925 using a D65 illuminant.

In aspects, the coated article 101 can be folded about the folding axis 102 in the direction 108 (e.g., see fig. 1) to form the coated article 201 in a folded configuration (e.g., see fig. 4-5). As shown, the coated article may include a single folding axis to allow the coated article to include double folds, where, for example, the coated article may be doubled over. In other aspects, the coated article may include two or more fold axes, which may allow the coated article to include a tri-fold or other multi-fold structure.
Fig. 4-7 schematically illustrate example aspects of a coated article 401, 601, or 701 according to aspects of the present disclosure in a folded configuration. Although not shown, the coated article may be folded such that the coating 113 is on the inside of the folded coated article and the second major surface 107 or 207 of the substrate 103 or 203 is on the outside of the folded coated article. If the display device is mounted on the second major surface 107 or 207 of the substrate 103, the user will view the device containing the coated article through the coating 113 and the substrate 103, and will thus view from one side of the first major surface 105 of the substrate 103 (e.g., from one side of the third major surface 115 of the coating 113). Alternatively, as shown in fig. 5 and 7, the coated article may be folded such that the coating 113 is on the outside of the folded coated article and the second major surface 107 of the substrate 103 is on the inside of the folded coated article. If the display device is mounted on the second major surface 107 of the substrate, the user will view the device containing the coated article through the coating 113 and the substrate 103, and will thus view from one side of the first major surface 105 of the substrate 103 (e.g., from one side of the third major surface 115 of the coating 113). In this alternative configuration, the coated article may be curved in a direction such that the second major surface 107 faces itself (similar to the configuration in fig. 5 or 7) or in a direction such that the first major surface 105 faces itself (not shown). If the display device is mounted on the test adhesive layer 609 in the position of the PET sheet 607 shown in fig. 7 or on the eighth major surface 265 of the adhesive layer in the position of the release liner 271, the user will view the device containing the coated article through the coating 113 and the substrate 103 and will therefore view from one side of the first major surface 205 of the substrate 203.
As used herein, "foldable" includes fully folded, partially folded, bent, flexed, or multiple capabilities. As used herein, the term "fail" and similar terms refer to breakage, damage, delamination, or crack propagation. If a foldable substrate (e.g., substrate, coating, coated article) resists failure when held at a parallel plate distance "X" of about 60 ℃ and about 90% relative humidity for 24 hours, the substrate achieves a parallel plate distance "X" or a parallel plate distance having "X".
As used herein, the "parallel plate distance" of a foldable substrate (e.g., substrate 103 or 203, coating 113, coated article 101, 201, 301, 401, 601, and/or 701) is measured by the following test configuration and method of using a parallel plate apparatus 501 (see fig. 5-7) that includes a pair of parallel rigid stainless steel plates 503 and 505 that includes a first rigid stainless steel plate 503 and a second rigid stainless steel plate 505. When measuring the "parallel plate distance" of the coated article 401, as shown in fig. 5, the coated article 401 is placed between the pair of parallel rigid stainless steel plates 503 and 505 such that the coating 113 (e.g., the third major surface 115) is on the outside of the bend (e.g., facing and/or contacting the stainless steel plates 503 and 505) and the substrate 103 (e.g., the second major surface 107) is on the inside of the bend (facing itself). When measuring the "parallel plate distance" of a coated article (e.g., coated article 201) comprising an adhesive layer 261, the adhesive layer 261 and any article disposed on the adhesive layer (e.g., release liner) are removed and replaced with a test adhesive layer 609 having a thickness of 50 μm and an elastic modulus of 0.1MPa at the location of the adhesive layer such that the first major surface 611 of the test adhesive layer 609 contacts the surface contacted by the adhesive layer (e.g., second major surface 207 in fig. 2 and 6, second surface region 325 and fourth surface region 335 in fig. 3 and 7), and the second major surface 613 of the test adhesive layer 609 contacts a 100 μm thick poly (ethylene terephthalate) sheet 607. When measuring the "parallel plate distance" of the coating 113 independent of a particular substrate, the fourth major surface 117 of the coating 113 is attached to a test adhesive layer comprising a thickness of 50 μm and an elastic modulus of 0.1MPa, which is attached to a 100 μm thick poly (ethylene terephthalate) sheet, and the combined laminate is placed between a pair of parallel rigid stainless steel plates 503 and 505 such that the coating 113 (e.g., the third major surface 115) is on the outside of the bend (e.g., facing and/or contacting the stainless steel plates 503 and 505). The distance between the parallel plates decreases at a rate of 50 microns/second until the parallel plate distance 507 is equal to the "parallel plate distance" to be tested. Subsequently, the parallel plates were held at about 60 ℃ and about 90% relative humidity for 24 hours at the parallel plate distance to be tested. As used herein, a "minimum parallel plate distance" is the minimum parallel plate distance that a foldable substrate (e.g., substrate 103 or 203, coating 113, coated article 101, 201, 301, 401, 601, and/or 701) can withstand without failing under the conditions and configurations described above.
In aspects, the coated article 101, 201, 301, 401, 601, and/or 701 and/or the coating 113 can achieve a parallel plate distance of 100mm or less, 50mm or less, 20mm or less, or 10mm or less. In other aspects, the coated article 101, 201, 301, 401, 601, and/or 701 and/or the coating 113 can achieve a parallel plate distance of 10 millimeters (mm) or 7mm, or 5mm, 4mm, 3mm, 2mm, or 1 mm. In aspects, the coated article 101, 201, 301, 401, 601, and/or 701 and/or the coating 113 can include a parallel plate distance of about 10mm or less, about 7mm or less, about 5mm or less, about 4mm or less, about 1mm or more, about 2mm or more, or about 3mm or more. In aspects, the coated article 101, 201, 301, 401, 601, and/or 701 and/or the coating 113 can include a parallel plate distance in a range of about 1mm to about 10mm, about 2mm to about 10mm, about 3mm to about 7mm, about 3mm to about 5mm, about 3mm to about 4mm, or any range or subrange therebetween.
In aspects, the coating 113 can withstand cyclic bending testing. As used herein, cyclic bending testing includes placing a test apparatus including a material to be tested in a parallel plate apparatus 501 (see fig. 5) and bending a laminate including a coating 113, as described above for the parallel plate test of the coating 113, to achieve a predetermined parallel plate distance between the plates 503, 505, repeated a predetermined number of times at 23 ℃,50% relative humidity. The test apparatus included attaching a 100 μm material portion of the coating 113 to be tested to a 100 μm thick PET sheet having a 50 μm thick adhesive with an elastic modulus of 0.1MPa, with the coating facing the pair of rigid stainless steel plates 503 and 505. In an aspect, the coating 113 can withstand 2,000 bending cycles at a parallel plate distance of 3 millimeters. In other aspects, the coating 113 can withstand 20,000 bending cycles at a parallel plate distance of 3 millimeters. In even other aspects, the coating 113 can withstand 200,000 bending cycles at a parallel plate distance of 3 millimeters. In an aspect, the coating 113 can withstand 2,000 bending cycles at a parallel plate distance of 4 millimeters. In other aspects, the coating 113 can withstand 20,000 bending cycles at a parallel plate distance of 4 millimeters. In even other aspects, the coating 113 is subjected to 200,000 bending cycles at a parallel plate distance of 4 millimeters.
The coated article may have an impact resistance as defined by the coating 113 and/or the coated article 101, 201, 301, 401, 601, and/or 701 to avoid failure at a certain pen-down height (e.g., 5 centimeters (cm) or more, 8cm or more, 10cm or more, 12cm or more, 15cm or more) when measured according to the "pen-down test". As used herein, a "pen drop test" is performed such that a sample of a coated article is tested by a load (i.e., from a pen dropped from a certain height) applied to the outer surface of the coated article and/or the coating configured as a parallel plate test (e.g., the third major surface 115 of the coating 113 in fig. 1-3, the second major surface 107 of the substrate 103 in fig. 1-3). During testing, the laminate comprising coating 113 and/or coated article 101, 201, 301, 401, 601 and/or 701 was placed on an aluminum plate (6063 aluminum alloy, polished to a surface roughness with 400 sandpaper). The side of the sample placed on the aluminum plate was not adhesive tape.
In the pen drop test, the pen used was a tungsten carbide ball-point pen comprising a diameter of 0.7mm (0.68 mm) and a BIC super-smooth pen comprising a cap weight of 5.73 grams (g) (without cap 4.68 g). The ballpoint pen is maintained at a predetermined height from an outer surface (e.g., the third major surface 115 of the coating 113 in fig. 1-3, the second major surface 107 of the substrate 103 in fig. 1-3) comprising the coating and/or the coated laminate. A tube was used for the pen drop test to guide the ballpoint pen to the outer surface of the coated article and the tube was placed in contact with the outer surface of the coated article such that the longitudinal axis of the tube was substantially perpendicular to the outer surface of the coated article. The tube had an outer diameter of 1 inch (2.54 cm), an inner diameter of sixteen nine inches (1.4 cm) and a length of 90cm. For each test, an acrylonitrile butadiene ("ABS") spacer was used to hold the ballpoint pen at a predetermined height. After each drop, the tube is repositioned relative to the outer surface of the sample to be tested to direct the ballpoint pen to a different impact location on the outer surface of the sample to be tested. It should be understood that the pen drop test may be used with any of the coatings and/or coated articles of aspects of the present disclosure.
For the pen drop test, the ballpoint pen is dropped with the cap attached to the tip (and the end opposite the tip) so that the ballpoint pen can interact with the outer surface of the coating (e.g., the third major surface 115 of the coating 113 in fig. 1-3, the second major surface 107 of the substrate 103 in fig. 1-3). In the falling sequence according to the pen drop test, one pen drop is performed at an initial height of 1cm, followed by continuous falling in 0.5cm increments up to 20cm, and then after 20cm, falling in 2cm increments until the sample to be tested fails. After each drop was made, any observable evidence of breakage, failure or other damage to the coated article was recorded, as well as the specific predetermined height of the pen drop. Using the pen drop test, multiple samples can be tested according to the same drop sequence to generate an ensemble of improved statistical accuracy. For the pen drop test, after every 5 drops and for each new coated article tested, the ballpoint pen was replaced with a new pen. In addition, unless otherwise indicated that no pens were falling near or on the edges of the coated article, all pens were falling at random locations on the coated article at or near the center of the coated article.
For the purposes of the pen drop test, "failure" means the formation of a visible mechanical defect in the sample. The mechanical defect may be a crack or plastic deformation (e.g., surface indentation). The crack may be a surface crack or a through crack. Cracks may form on the inner or outer surface of the sample. The crack may extend through the coating 113 and/or all or a portion of the coated article 101, 201, 301, 401, 601, and/or 701. The smallest dimension of the visible mechanical defect is 0.2 mm or more. In aspects, the coating 113 and/or the coated article 101, 201, 301, 401, 601, and/or 701 can withstand a pen-drop height of 1cm or greater, 3cm or greater, 5cm or greater, 7cm or greater, 8cm or greater, 9cm or greater, 10cm or greater, 11cm or greater, 12cm or greater, 13cm or greater, 14cm or greater, 15cm or greater, 16cm or greater, 17cm or greater, 18cm or greater, 19cm or greater, and/or 20cm or greater above the third major surface 115 of the coating 113.
For a coated article comprising one or more recesses (e.g., first recess 234, second recess 241) and/or a minimum distance 343 between different portions (e.g., first portion 321 and second portion 331), for example, similar to fig. 2-3, for a coated article having a substrate thickness of 30 μm or greater, the coated article may withstand a pen-drop height of 5cm or greater, 8cm or greater, 10cm or greater, 12cm or greater, 13cm or greater, 14cm or greater, or 15cm or greater over a portion of third major surface 115 (corresponding to the minimum distance between the recesses and/or different portions). For a coated article comprising one or more recesses, e.g., similar to fig. 2, for a substrate having a thickness of 30 μm or greater, the coated article can withstand a pen-down height of about 10cm or greater, 15cm or greater, 17cm or greater, 18cm or greater, 19cm or greater, or about 20cm or greater on a portion (e.g., first portion 221, second portion 231) of the third major surface 115 or second major surface 107 that does not comprise recesses.

Examples JJ-LL correspond to examples A-B and AA, respectively, but the cured composition comprises a cured composition having a J/cm of 2.54 2 The coating was irradiated by irradiating the composition for 5 minutes without subsequent heating of the composition.

The adhesion values reported in table 15 were measured on samples formed without further processing examples using the cross-line adhesion test described above. Examples B, AA, KK-LL, NN-OO, RR, BBB-EEE, GGG-MMM, FFF-100-KKK-100, RRR, TTT-YYY, AAAA-DDDD, and FFFF-HHHH include an adhesion of 3B or more. Examples LL, OO, BBB-EEE, GGG-MMM, FFF-100-III-100, RRR, TTT-YYY, CCCC, and FFFF-HHHH include an adhesion of 4B or greater. Examples GGG-JJJ, FFF-100-JJ-100, TTT-YYY and FFFF-HHH include 5B adhesion. Examples A-B, AA-BB, JJ-RR, BBB, FFF, LLL-MMM, OOO-PPP and SSS include pen hardness of 5H or greater. Examples A-B, AA-BB, JJ-RR, FFF, LLL-MMM and OOO-PPP included pen hardness of 6H or greater. Examples A-B, BB, JJ-KK and MM-QQ included pen hardness of 7H or more. Examples B, BBB, JJ-KK and MM-RR included pen hardness of 8H or more. Examples B, BB, JJ-KK, MM-NN and PP-QQ included pen hardness of 9H or more. Examples B, KK-LL, NN, RR, BBB and LLL-MMM include pen hardness of 5H or greater and adhesion of 3B or greater. Examples B, KK, NN-OO and RR included a pen hardness of 8H or greater and an adhesion of 3B or greater. Examples LL, OO, BBB and LLL-MMM included pen hardness of 5H or greater and adhesion of 4B or greater. Examples LL, OO and LL-MMM include pen hardness of 6H or greater and adhesion of 4B or greater. The example BBB includes a pen hardness of 5H or greater and an adhesion of 4B or greater. Example NNN cracked during cure. The QQQ of example phase-separates so that a uniform coating cannot be formed.
Providing a linking group increases the pen hardness of the coating (compare example AAA with example BBB-FFF). The provision of a curing catalyst increases the pen hardness of the coating (compare examples BBB, III, III-100, KKK-100 with examples CCC, JJJ, JJJ-100, LLL). The polymeric linking group D400 (example RRR) provided the highest adhesion as compared to example QQQ-SSS. The addition of TMPO improved the adhesion and pen hardness of the coating (compare example RRR with examples TTT-XXX). Prior to curing, example ggggg-hhhhhh includes GPOSS connected by PDMS1, which provides a pen hardness of about 4H or greater and an adhesion of 5B or greater.
Table 15: hardness, adhesion and thickness of the coating (as formed)
The adhesion values reported in tables 16-17 were measured using the cross-line adhesion test described above after the coating (e.g., coated article) had been maintained at 95 relative humidity for 10 days in a 65 ℃ environment. The coatings of the examples reported in table 16 were deposited in the absence of surface treatments or silane coupling agents. Examples A-B, JJ-KK and MM-RR included pen hardness of 7H or greater. Examples B, JJ-KK, MM-NN and PP-QQ included 9H pen hardness. Examples B, JJ-LL, NN-OO and RR included adhesion of 1B or greater. Examples B, KK-LL, NN-OO and RR included adhesion forces of 3B or greater. Examples LL and OO include adhesion of 4B. Examples A, MM and PP-QQ included an adhesion of 0B. Comparing examples A-B, AA, JJ-LL with examples MM-RR, the total energy density of the irradiated composition did not significantly change the resultant adhesion, although the hardness may be slightly higher the total energy density. Unexpectedly, because it is expected to increase the total energy density to 10J/cm 2 Or even 20J/cm 2 Or higher will be apparentSignificantly improving adhesion and/or hardness. Thus, from the use of 2.54J/cm 2 The pen hardness and adhesion of the composition cured by irradiation of the total energy density of (c) provides the unexpected benefits of reduced energy and time required, while yielding corresponding coating properties. Examples in table 16 based on example B (i.e., examples B, KK, NN, and QQ) included a hardness of 9H, while examples in table 16 based on example AA (i.e., examples AA, LL, OO, and RR) included a hardness of 8H or less.
Examples AA-CC are comparative examples. Unlike examples A-W, example AA does not contain any polymer. It is still possible to form the coating using the method described above, and the composition is visually transparent. However, the examples based on example AA (i.e., examples AA, LL, OO, and RR) included a hardness of 8H or less that was less than the 9H hardness achieved for the examples based on example B (i.e., examples B, KK, NN, and QQ). Unlike examples a-W, example BB includes a polymer having functional groups at only one end of the polymer chain, not at both ends. Thus, the polymer of example BB may not attach a first functionalized oligomeric silsesquioxane to another functionalized oligomeric silsesquioxane. Indeed, the composition of example BB was not visually clear when the solvent was removed. In contrast, when the solvent is removed, the composition of example BB is opaque white, which may be the result of the aggregation of the functionalized oligomeric silsesquioxane. Embodiment BB may not be applied to form a coating in the same manner as described for embodiments a-G, as irregular and/or segmented coatings will be formed. Thus, the coatings based on example BB required curing using a multi-step heating process to evaporate the solvent over 8 hours or more, which was significantly longer than the 5 minute UV radiation and even 30 minute heating experienced by some of examples A-W and JJ-RR. Example BB included an adhesion of 0B, which could not withstand 10 days without visible delamination or cracking in a 95% relative humidity, 65℃environment. Unlike examples A-W, example CC does not include any functionalized oligomeric silsesquioxane. In contrast, example CC includes silica nanoparticles and a linking group. Although example CC included an adhesion of 5B, example CC included a hardness of 0H, but was lower than the other examples. Therefore, example CC is not suitable as a hard coat layer.

GOPTMS refers to (3-epoxypropyloxypropyl) trimethoxysilane available as 440167 from Sigma Aldrich, as Coatosil MP200 from Momentive, or as SIG5840.0 from Silquest. Ecletms refers to 2- (2, 4-epoxycyclohexyl) ethyl trimethoxysilane available as SIE4670.0 from Gelest or Silquest a186 from Momentive. TEPSA refers to (3-triethoxysilyl) propyl succinic anhydride available as SIT8192.6 from Gelest. MPTMS refers to (3-mercaptopropyl) trimethoxysilane available from Gelest as SIM 6476.0. Examples S-Z included coatings of example D attached to the substrate using the treatments indicated in table 17. The plasma treatments of examples TT, VV, XX and ZZ were performed prior to depositing any silane coupling agent and included exposing a surface (e.g., the first major surface) of the substrate to atmospheric plasma for 1 minute in a 25 ℃ environment.
Examples A, BB, SS, UU-WW and YY included an adhesion of 0B and were not subjected to plasma treatment prior to deposition of the silane coupling agent, as shown in table 17. Examples TT and ZZ include an adhesion of 1B or more and are plasma treated prior to the deposition of the silane coupling agent, while examples VV and XX include an adhesion of 0B even if plasma treatment is present prior to the deposition of the silane coupling agent. This demonstrates the unexpected benefit of APTMS and TEPSA that these silane coupling agents can improve the adhesion of the coating, while other silane coupling agents may not even be combined with plasma treatment. In addition, the results in Table 17 demonstrate that providing a surface treatment (e.g., a plasma treatment) prior to depositing the silane coupling agent can improve the adhesion of the coating.

Table 18: surface treatment, hardness and adhesion (as formed) of the coating
Unlike in table 17, the adhesion and hardness measurements reported in table 18 were measured on the coating of the coated article when formed. The substrates of examples M-N and P were treated with plasma prior to deposition of the composition. Examples H-I and O were coated with a 2wt% solution of the thiol-functionalized silane coupling agent MPTMS and heated at 100℃for 30 minutes. Examples M-N include compositions containing silane coupling agents, as shown in Table 4. Examples H-U include a hardness of 7H or greater. Examples H-I, K, M-P and R-U include hardness of 8H or more. Examples M-P and R-U included a hardness of 9H. Examples H-W include adhesion of 1B or greater. Examples H-K, M and O-W included adhesion of 2B or greater. Examples H-K, M, O, Q and S-W included adhesion of 3B or greater. Examples H, J-K, O, T and V-W include adhesion of 4B or greater. Examples J-K included 5B adhesion. Examples H-K, M and O, Q, S-U include a hardness of 7H or more and an adhesion of 3B or more. Examples H, K, O and T include an adhesion of 8H or greater and an adhesion of 4B or greater.
The adhesion values reported in table 19 were measured after the coating (e.g., coated article) had been held at 85% relative humidity in an environment of 85 ℃ for 30 minutes using the cross-line adhesion test described above. The coatings of the examples reported in table 19 were deposited without surface treatment or silane coupling agents. Examples GGG-RRR, GGG-100-JJJ-100, TTT-XXX, AAAA-DDDD, and FFFF-HHH include an adhesion of 3B or more. Examples GGG-JJJ, GGG-100-JJJ-100, UU-VVV, XXX, CCCC-DDDD, and FFFF-HHHH include an adhesion of 4B or more. Examples GGG-JJJ, GGG-100-JJJ-100, XXX, DDDD and GGGG-HHHH include an adhesion of 5B or more.
Table 19: hardness, adhesion and thickness of the coating (30 min at 85 ℃ C., 85% relative humidity)
In table 20, the pen-down heights of coated articles similar to the coated article 301 shown in fig. 3 are reported. The substrate 103 comprises composition 1 and the substrate thickness 109 is 30 μm. The first portion 321 and the second portion 331 comprise composition 1 and the partial thickness 329 is 30 μm. The coating 113 includes a coating thickness 119 of 30 μm. The coating was formed by curing the composition of example E. The median pen drop height was 17cm when the pen drop was performed on the second surface area 325 of the first portion 321. The median pen drop height was 16cm when the pen drop was performed on the third major surface 115 of the coating 113 extending along the fourth plane 306. The control was a 30 μm thick substrate containing composition 1, comprising a median pen drop height of 7.4 cm. Thus, providing a coating increases the median pen drop height of the two areas tested. Specifically, the median drop height above the coating (i.e., the third major surface 115 extending along the fourth plane 306) is only 1cm (6%) below the median drop height above the first portion.

The parallel plate distance of a coated article similar to the coated article 201 shown in fig. 2 and 6 was measured. The substrate 203 comprises composition 1 and has a substrate thickness 209 of 100 μm and a center thickness 289 of 30 μm. The coating 113 includes a coating thickness 119 of 30 μm. The coating was formed by curing the composition of example E. After 10 days in a 25 ℃ environment at 50% relative humidity, the coated article achieved a parallel plate distance of 3 mm. In addition, the coated article as formed was able to withstand 200,000 cycles of bending to a parallel plate distance of 3 mm.
The above observations can be combined to provide compositions, coatings, and coated articles comprising a variety of functionalized oligomeric silsesquioxanes, as well as methods of making such compositions, coatings, and coated articles. A variety of functionalized oligomeric silsesquioxanes can provide good scratch resistance and/or high pen hardness (e.g., about 5H or greater, about 7H or greater, about 9H or greater). Providing a plurality of functionalized oligomeric silsesquioxanes can react with a first functional group and/or a second functional group of a linking group (e.g., a polymer). The degree of functionalization of the plurality of functionalized oligomeric silsesquioxanes may facilitate the binding of a linking group (e.g., a polymer) to two different ones of the plurality of functionalized oligomeric silsesquioxanes. Providing a coating on the substrate improves the durability of the coated article, for example by filling surface defects in the substrate and/or protecting the surface defects in the substrate from damage. In addition, the substrate may include a glass-based substrate and/or a ceramic-based substrate to enhance puncture resistance and/or impact resistance. In addition, the glass-based substrate and/or ceramic-based substrate may be chemically strengthened to further enhance the impact and/or puncture resistance of the coated article while promoting good bending properties.
The composition may comprise a linking group (e.g., a polymer) having a functional group at an opposite end of the linking group (e.g., a polymer), wherein the functional group reacts with the functionalized oligomeric silsesquioxane. The linking group may include a polymer that may reduce (e.g., prevent) aggregation of the various functionalized oligomeric silsesquioxanes, may provide good optical properties (e.g., high transmittance, low haze), and as a coating, may provide good durability and/or good adhesion to the substrate. Providing a linking group (e.g., a polymer) that includes oxygen atoms in the backbone of the linking group (e.g., a polymer) can increase the flexibility of the linking group, the resulting composition, and the resulting coating, which can increase the ultimate elongation, durability, and/or impact resistance (e.g., pen drop height). Providing a linking group comprising a polymer having a number average molecular weight (Mn) in the range of about 400 daltons to about 30,000 daltons can prevent aggregation of the functionalized oligomeric silsesquioxane attached thereto while reducing entanglement of the polymer, which can inhibit manufacturability of the resulting coating and/or coated article. Providing a low molar ratio of linking groups (e.g., polymer) to the various functionalized oligomeric silsesquioxanes (e.g., about 0.06 or less) can result in a polymer that binds to both functionalized oligomeric silsesquioxanes, which can achieve the benefits described above. Providing a polymer having a glass transition temperature outside the operating range of the coated article (e.g., outside the operating range of about-20 ℃ to about 60 ℃) may result in a coated article having consistent properties over the operating range. Providing a reactive diluent (e.g., a linking group that is not bonded to the functionalized oligomeric silsesquioxane prior to curing after the composition is disposed on a substrate) can be used to adjust the viscosity of the composition, which can facilitate uniform application and/or enable lower cost application techniques while reducing the overall cost of the composition and/or coating.
Providing a linking group comprising one or more amine and/or anhydride functional groups can provide a coating that has good adhesion to a substrate (e.g., about 4B or greater when formed, about 4B or greater after 10 days of holding at 50% relative humidity in a 25 ℃ environment, and/or about 4B or greater after 10 days of holding at 95% relative humidity in a 65 ℃ environment), whether or not a silane coupling agent is used. Providing a curing catalyst may increase the hardness of the resulting coating. Providing a composition comprising trimethylol propane oxetane can increase the hardness of the resulting coating. The coating may be hydrophobic, have a low dynamic coefficient of friction (i.e., about 0.8 or less, such as about 0.5 or less), good abrasion resistance, and/or function as an easy-to-clean (ETC) coating.
Forming the layer from a substantially solvent-free composition may increase its cure rate, which may reduce processing time. Furthermore, solvent-free compositions may reduce (e.g., reduce, eliminate) the use of rheology modifiers and increase composition uniformity, which may increase the optical clarity (e.g., transmittance) of the resulting coating. Furthermore, the solvent-free composition may reduce the incidence of visual defects (e.g., bubbles generated by volatile gases upon evaporation of any solvent) in the resulting coating. Providing a coating process that includes a solvent may enable a wide variety of compositions to be used to form a coating. In addition, the layer is cured by irradiating the layer for a short time to form a coating layer, which can improve the processing efficiency and reduce the manufacturing cost. Providing the composition with additional functionalized oligomeric silsesquioxane to form the layer may further increase the hardness of the resulting coating and/or coated article. Providing a composition that does not contain a photoinitiator (e.g., a thermosetting composition) may not present yellowing problems. Providing a silane coupling agent can increase the adhesion of the coating to a substrate (e.g., glass-based substrate, polymer-based substrate). In addition, the coating may include high light transmittance (e.g., about 90% or greater), low haze (e.g., about 0.5% or less), and/or low yellowing index (e.g., about 0.6 or less). Providing a composition that is substantially free and/or free of nanoparticles (e.g., silica nanoparticles, alumina nanoparticles) may reduce handling problems (e.g., agglomeration, aggregation, phase separation) of the composition, improve optical properties (e.g., maintain low haze and/or high transmittance even after aging at elevated temperatures and/or humidity) of the coating and/or resulting coating and/or coated article, and reduce mechanical properties (e.g., hardness, modulus, strain) of the resulting coating and/or coated article, as compared to a corresponding composition, coating and/or coated article that includes a plurality of functionalized oligomeric silsesquioxanes without nanoparticles (e.g., silica nanoparticles, alumina nanoparticles).
