Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conductive transfer film,

[0001] The present invention relates to a conductive transfer film for use in a receptacle, which can be adhered not only to a flat substrate but also to a to-be-transferred object having a curved surface and a curvature, and a coating method using the same.

In recent telecommunication and electronic devices fields, researches on development of transparent and flexible devices have been emphasized in order to meet the requirements of high portability and aesthetic factors in addition to the tendency to miniaturize, lightweight, thinner and environmentally friendly materials.

For example, the transparent conductive film has a structure in which a transparent conductive thin film is formed on a transparent polymer substrate and widely used for a display, an EL backlight, a touch panel, a solar cell, and an electromagnetic wave shielding material.

In particular, recently, the introduction rate of touch panels to electronic devices called mobile phones and tablet PCs is increasing, and the demand for conductive films is rapidly expanding.

In order for the conductive film to be used as a material for electronic parts, it has high conductivity, transparency, and excellent adhesion.

Since recently used conductive films are required to have uniformity in thickness and durability in addition to flexibility and transparency, they are excellent in electrical conductivity with a sheet resistance of 500 Ω / sq or less on a substrate, and transmittance in a visible light region of 380 to 780 nm is 80% The above transparent conductive film is preferably used.

Examples of the conductive film material include a metal oxide such as indium tin oxide (ITO), a metal nanowire such as silver nanowire, a carbon material such as carbon nanotube (CNT) or graphene, or a conductive polymer such as a conducting polymer ).

These conductive films usually have a thickness on the order of microns and are produced by a coating method such as a vacuum deposition method such as sputtering or a spray coating method. In this method, there is no problem in the case where the object on which the conductive film is formed is flat. However, it is impossible to form a uniform thickness in curved surfaces such as a display or a folding display in which a recent interest is rapidly increasing. Especially, do. Furthermore, in the case of molded articles of 3-D structure having various shapes of unevenness and curvature, it is almost impossible to secure a uniform thickness.

On the other hand, among the coating methods, the transfer coating is separated into a transfer material, a thermal transfer material, a vacuum transfer material, and the like depending on the manner of transferring the printed matter or the pattern shape to the transfer object. That is, if the transferring medium is water, it is called a hydrostatic transferor, if it is heat, it is thermal transfer, and if it is vacuum, it is called vacuum transfer.

Among them, a water transfer (calf process, water transfer) uses a water transfer transfer film, which is made of a coating layer having various patterns and colors on a PVA film dissolved in water. The PVA film of the transfer film is dissolved by water during the transfer and selectively coated with only the coating layer. Such a transfer sheet can print a desired pattern on all the curved surfaces, and it is possible to coat various colors or patterns on the surface of various materials.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a conductive transfer film according to a first embodiment of the present invention. FIG.

1, the receptive conductive transfer film 10 has a structure in which an acceptor layer 11, a base layer 13, a conductive coating layer 15, and an overcoat layer 17 are sequentially laminated.

The acceptor layer (11) is a layer which is decomposed and peeled off by water during hydration. As the acceptor layer 11, a water-soluble polymer material may be used. Typically, the water-soluble polymer is selected from the group consisting of dextrin, polyvinyl alcohol, polyvinyl pyrrolidone, polyacrylamide, polyvinyl methyl ether, poly (meth) acrylic acid-containing polymer, etherified starch, starch, One type is possible, and preferably dextrin or polyvinyl alcohol is used.

In order to further improve water retention, a polymeric absorber such as polyethylene glycol or hydrogel may be added.

The receiving layer 11 may have a thickness of 1 to 1000 탆, preferably 5 to 500 탆, and may have a different thickness depending on the field to which it is applied. If the thickness is less than the above-mentioned range and the thickness is too thin, the coating speed of the transfer target body is not easily controlled when the transfer is too slow, The coating quality of the transfer film may be deteriorated.

The base layer 13 is a layer which is located on the acceptance layer 11 and is directly attached to the receptor as the acceptance layer 11 is removed during the water transfer. The base layer 13 is preferably made of a flexible material having adhesiveness or adhesiveness to a body to be applied, as well as flat surfaces, curved surfaces and curved surfaces.

As the usable base layer 13, there can be used the above-mentioned materials such as polyethylene terephthalide, polyethylene naphthalate, polyurethane, polyacrylate, polyimide, polyethersulfone, polyetherimide, polyphenylene sulfide, polyarylate, polycarbonate , A cycloolefin polymer (COP), a cycloolefin copolymer (COC), cellulose triacetate, cellulose acetate propionate (CAP), a norbornene resin, and combinations thereof.

Various fillers may be added to the base layer 13 to prevent blocking. Examples of the filler include fluorine resin particles, melamine resin particles, silicone particles, talc, kaolin, magnesium carbonate, potassium carbonate, titanium oxide, .

These substrate layers 13 may be in the form of a single film or in the form of a multilayer film of two or more layers. The multi-layer film may be formed by different kinds of materials of the base layer 13.

The thickness of the base layer 13 may vary depending on the intended application and can be appropriately adjusted by those skilled in the art.

For example, when used in a display or a touch panel, it is 15 to 150 mu m, preferably 20 to 60 mu m. If the thickness is less than the above range and the thickness is too thin, coating on the body is not easy, and on the contrary, when the thickness exceeds the above range, coating on the curved surface may not be completely performed. .

The conductive coating layer 15 is a coating layer containing one kind of conductive material selected from the group consisting of a metal nanomaterial, a transparent conductive oxide, a carbon material, a conductive polymer, and a combination thereof.

Wherein the metal nanomaterial is a metal nanowire including a metal selected from the group consisting of Ag, Au, Cu, Pt, Fe, Co, Ni, Zn, Ru, Pd, Nano-rod, preferably a metal nanowire. Silver nanowires (AgNW) are preferably used.

In consideration of lumpiness or dispersibility of the nanowires, a length of 0.5 to 100 mu m, preferably 1 to 40 mu m is used.

In particular, the silver nanowire has the highest conductivity among metals and has a resistance value of 30 to 120 OMEGA, which is less than 200 to 400 OMEGA. In addition, since the transparent conductive layer made of silver nanowires is almost colorless, the color of the image can be faithfully expressed when the display is applied. In addition, silver nanowires are flexible in a thin and long form It is especially useful for flexible displays.

Transparent conductive oxides include indium tin oxide (ITO), indium zinc oxide (IZO), indium zinc tin oxide (IZTO), zinc oxide (ZnO), tin oxide (TO), cadmium tin oxide (CTO) (AZO) doped with aluminum, zinc oxide doped with gallium (GZO), and a combination thereof, are used as the anode active material .

The conductive coating layer 15 may be in the form of a single film or a laminated film.

At this time, the thickness of the conductive coating layer 15 may vary depending on the application to be applied and can be appropriately adjusted by those skilled in the art.

For example, when used in a display or a touch panel, it is 15 to 150 mu m, preferably 20 to 60 mu m. If the thickness is less than the above range and the thickness is too thin, the conductivity is too low to perform the function of the conductive coating layer. On the contrary, if the thickness exceeds the above range, cracks may occur during coating of curved or curved surfaces. .

The overcoat layer 17 not only protects the surface of the transfer film 10 but also improves the adhesion of the conductive coating layer 15 to the base layer 13.

At this time, the material of the overcoat layer 17 is suitable for the above-mentioned role, and any material that can be photopolymerized or thermally cured can be used. For example, it is selected from the group consisting of a polyacrylic resin, a polyurethane resin, a polyolefin resin, a polyester resin, an epoxy resin, a melamine resin, a polyamide resin, a polycarbonate resin, a cellulose resin, One type of material is used and is not particularly limited in the present invention.

The thickness of the overcoat layer 17 is not particularly limited in the present invention, but is preferably 10 to 500 nm, more preferably 20 to 300 nm. If the thickness is less than the range, there is a problem that the surface protective property of the transfer film 10 is deteriorated. Conversely, if the thickness exceeds the range, cracks may occur during coating of curved or curved surfaces.

The above-described electrically conductive transfer film 10 for use in a power supply described above may further include known additives in the manufacturing process of each layer, and is not specifically mentioned in the present invention.

The conductive transfer film according to the first embodiment having the above structure can be applied to various fields, and various functional layers may be inserted between the layers or between the layers depending on the application field.

At this time, the material of each layer is not particularly limited in the present invention, and a known material can be selected, and the thickness can be variously applied depending on the use.

The metal layer may function as a metal wiring or an additional electrode or sensor layer in electrical contact with the conductive transfer film when the conductive transfer film is used as an electrode. At this time, the metal layer may be laminated on the upper and lower parts thereof or on the overcoat layer so as to form a laminated structure with the conductive transfer film.

The conductive transfer film for use in the invention according to the present invention is based on a known method for producing a multilayer film and is not particularly limited in the present invention.

For example, a hydrantable conductive transfer film may be formed by forming a substrate layer on a receiving layer, forming a conductive coating layer on the substrate layer, and forming an overcoat layer on the conductive coating layer.

At this time, each layer can be formed by a dry or wet coating process.

Examples of the dry coating process include a sputtering process, an E-beam evaporation process, a thermal evaporation process, a laser molecular beam epitaxy (L-MBE) process, and a pulsed laser deposition process (PLD) Chemical vapor deposition (CVD) using chemical methods such as MOCVD (Metal-Organic Chemical Vapor Deposition) and HVPE (Hydride Vapor Phase Epitaxy), and physical vapor deposition (PVD) using physical methods such as pulsed laser deposition Do.

The conductive transfer film according to the present invention can be applied not only to a flat plate but also to various substrates having curved surfaces and curved surfaces with a uniform thickness and has electrical conductivity over the entire coating film and can be applied to various fields.

Such a coating using a water-transfer conductive transfer film

S1) flooding the conductive transfer film for use in a water tank,

S2) transferring the transferred body by pressing the transferred body over the electrically conductive transfer film; And

S3), followed by drying.

Each step will be described in more detail below.

First, in step S1), a water-use conductive transfer film is floated on the water tank.

At this time, the conductive transfer film is cut to a size slightly larger than the water tank so that the water surface in the water tank is sufficiently covered as a whole.

Next, in step S2), the transfer target is pressed onto the transfer receiving conductive transfer film to transfer the transfer film to the transfer target.

More specifically, as soon as the transfer object is brought into contact with the transferable conductive transfer film on the water tray, the transfer layer is accommodated in the transfer film, and the transfer layer is coated (adhered) with the substrate layer in contact with the surface of the transfer object.

The subject body does not limit its material or shape. For example, plastic materials such as PE, PP, PVC, PS, ABS, acrylic, and phenol resin; Metals such as iron, copper and aluminum; Ceramics such as glass, earthenware, ceramics, cement and calcium silicate; Woody plywood such as wood plywood, wood veneer, particle board; paper; Fiber, non-woven fabric, and the like.

In addition, as the form of the transferred body, a substrate having a flat plate, a curved surface or a curved surface is possible, and a known sheet, substrate, or various types of 3-D molded articles are possible.

At this time, the subject can be pretreated to improve the adhesive strength.

The pretreatment furnace may be a high frequency spark discharge treatment such as a corona treatment or a plasma treatment; Heat treatment; Flame treatment; Coupling agent treatment; Anchor treatment; Or a chemical activation treatment using gaseous Lewis acid (ex. BF ₃ ), sulfuric acid or high temperature sodium hydroxide, or the like.

Or to form a primer layer on the surface of the body to be bonded to increase the adhesive strength. The primer layer may be formed, for example, by treatment with an aqueous primer composition such as a polyacrylic resin, a polyurethane resin, or a polyester resin.

These pretreatment are not particularly limited in the present invention, and can be carried out by appropriately selecting known methods by those skilled in the art.

Next, after washing and drying in step S3), a product coated with a conductive transfer film on the surface of the body is obtained.

The water transfer agent performs the transfer in the tank by the term, so that a coating layer is formed by simple washing and drying.

The washing is carried out with water. The drying conditions are not particularly limited. For example, the drying is carried out at a temperature of room temperature to 100 DEG C, preferably about 25 DEG C to 100 DEG C for about 30 seconds to 30 minutes, 10 min. ≪ / RTI >

As a result, an environmentally friendly operation which is harmless to the human body and improved in work environment can be performed as compared with the use of various apparatuses and solvents for conventional coating, and there is an advantage that post treatment can be performed at a relatively low temperature.

The subject to be subjected to the above steps is coated with a multilayered conductive transfer film in which a base layer / a conductive coating layer / an overcoat layer are successively laminated on the surface thereof. Since the transfer film is manufactured to have a predetermined thickness designed before the transfer process, the thickness of the transfer film coated after the transfer is maintained to the initial designed thickness and has the same thickness over the entire coated surface. In particular, since it is free from flaking at corners or grooves, it is possible to maintain the originally designed thickness and to exhibit a uniform electrical conductivity as a whole.

FIG. 3 is a schematic view showing a state in which a conductive transfer film for use in a first embodiment of the present invention is coated on a flat substrate, and FIG. 4 is a schematic view showing a conductive transfer film used for a receptive layer coated on a molded article having a gentle bend. Referring to FIG. 3 and FIG. 4, it can be seen that the electrically conductive transfer film for power reception can be entirely coated on a flat or curved substrate.

The conductive transfer film for use in the present invention as described above can be applied to various fields as a conductive film while maintaining excellent electrical conductivity and thickness uniformity.

For example, electrodes or sensors of touch panels, transparent electromagnetic wave shielding films, transparent heating elements, conductive substrates, gas sensors, heat reflective coating films, solar cells, lighting and automobiles in addition to display fields such as LCDs, PDPs, OLEDs and FEDs Can be used. In particular, when the conductive coating layer is formed of a metal nanomaterial or a transparent conductive oxide, it can be applied as a transparent electrode.
