Definitions
- the present invention relates to a new ultra-thin hydrophobic and oleophobic layer formed by self-assembly on a solid substrate surface of catechol foot compounds, a process for preparing this ultra-thin layer and the use thereof as an epilame.
- the proper functioning of a watch movement depends, among other things, on its lubrication.
- the durability of the lubricant depends in particular on its maintenance in the operating zone: every watchmaker, however, has noticed that a drop of lubricant spreads rapidly over a clean part.
- the deposition of an epilame layer generally in the form of a hydrophobic and oleophobic invisible molecular layer, avoids the spreading of the lubricant and its components.
- the spreading of a liquid depends on the interaction forces between the liquid, the surface and the surrounding air (see JC Berg, “Wettability", Marcel Dekker, New York, 1993 and AW Adamson, “Physical Chemistry of Surfaces”. “, Wiley).
- the parameter that characterizes the interaction forces between a liquid and the air is the surface tension, ⁇ LV .
- a surface energy ⁇ sv between a solid and the surrounding air and a parameter ⁇ LS between the solid and the liquid are similarly defined.
- the Young equation also shows that if the surface tension of the liquid is lower than the surface energy, the contact angle is zero and the liquid wets the surface. This is what happens for a lubricant deposited on a clean metal surface: in In fact, a lubricant has a surface tension of 35-40 mN / m, whereas a common metal surface has a higher surface energy.
- this contact angle is about 30 °, whereas it is about 110 ° for a -CH 3 functional group (eg C 12 H 25 SH ) and about 118 ° for a -CF 3 functional group (eg, C 10 F 17 H 4 SH).
- a -CH 3 functional group eg C 12 H 25 SH
- a -CF 3 functional group eg, C 10 F 17 H 4 SH
- the deposition of the compound on the substrate is carried out by soaking it in a solution of perfluorinated solvent loaded with polymer.
- the solvent used is generally tetradecafluorohexane (C 6 Fi 4 ) which, once volatilized, is a greenhouse gas since it remains stable for 3200 years in the air and has a greenhouse potential of 7400 equivalents. CO 2 .
- the object of the invention is to propose compounds that can be used as epilame and that can be attached to a solid substrate surface.
- the invention indeed proposes a novel ultra-thin hydrophobic and oleophobic layer formed by self-assembly on a solid substrate surface of catechol foot compounds, and a process for preparing this ultra-thin layer which uses a non-fluorinated solvent, for example a mixture of water and 2-propanol. Thanks to the catechol foot of the compounds used, this ultra-thin layer is firmly fixed to the surface of the solid substrate. This ultra-thin layer has satisfactory properties for use as an epilame, particularly a contact angle in advance with water and a spread of a drop of oil, quite comparable to those of the layer obtained from the reference product Fixodrop FK-BS.
- the catechol foot compounds have the general formula
- A-B wherein A represents a group of formula
- Z represents C or N +
- X represents CH or CL, L being an electron-withdrawing group chosen from F, Cl, Br, I, CF 3 , NO 2 and N (CH 3 ) 3 + , Y represents H or CH 3, or Y forms with X a heterocycle of 5; or 6 atoms,
- T represents NH, NH-CO, NH-CO-NH or NH 2 + U " , U “ being a soluble anion, such as for example F “ , Cl “ , Br “ , I, OH “ , NO 3 “ , HSO 4 “ , SO 4 2” , CO 3 2 “ , HCO 3 “ or SCN " , and B represents an unsubstituted C 1 -C 20 aliphatic linear alkyl group.
- the group A serves in particular to allow the attachment of the compounds to the surface of the solid substrate through the catechol group and the solubilization of the amphiphilic molecule A-B in the dipping solution.
- Group B gives the ultra-thin layer its hydrophobic and oleophobic properties.
- Interesting groups A are those selected from one of the following groups:
- the compounds of formulas A-B can be obtained from known compounds using techniques and reactions well known to the organic chemist.
- (SuSoS1) can be obtained by reacting octadecylisocyanate and 3-hydroxy-tyramine hydrochloric acid in solution in DMF in the presence of N-methyl-morpholine.
- the solid substrate on the surface of which the self-assembly is made can be any solid substrate involved in the operation of a mechanical movement, in particular consisting of a material selected from among gold, silver, silver steel, including 20AP steel, aluminum, brass, bronze, cuproberyllium, titanium dioxide, ruby, sapphire, silicon, nickel and nickel-phosphorus, as well as other surfaces metal, such as iron, chromium, tantalum, yttrium, silicon, germanium, copper, platinum, and metallic or ceramic oxides, such as zirconia and niobium (niobium oxide), this list not being limiting.
- the substrate may also be a substrate in one of these materials or another whose surface has been coated or coated, for example by a galvanic deposition of gold, gold-copper-cadmium and gold, nickel, rhodium, d 1 tin-nickel, or treated by anodizing, as in the case of parts made of aluminum alloy or titanium, or modified by a surface treatment such as oxidation, carburization or nitriding.
- the thickness of the ultra-thin layer measured in ellipsometry is generally from 0.5 to 10 nm, which value will be higher for the definition of ultrathin, preferably from 1 to 4 nm.
- the contact angle in advance with the water must generally be at least 100 °.
- the contact angle in advance with the water must generally be at least 100 °.
- epilame a film whose contact angle may be substantially less than 100 °, for example between 90 and 100 °, but still prevents spreading, which remains less than 2%.
- the ultra-thin layer of formula A-B remains functional as epilame after two watch washes.
- the invention also relates to a timepiece characterized in that it comprises an ultra-thin layer as defined above.
- the invention also relates to a process for preparing the ultra-thin layer defined above, characterized in that it comprises immersing the substrate in a solution of the compound of formula AB, for example in water, or a mixture of water and protic solvent such as, for example, 2-propanol, or a mixture of an aprotic solvent and a solvent protic such as 2-propanol.
- a solution of the compound of formula AB for example in water, or a mixture of water and protic solvent such as, for example, 2-propanol, or a mixture of an aprotic solvent and a solvent protic such as 2-propanol.
- Octadecylisocyanate (668 mg, 2.26 mmol) was dripped into a solution of 3-hydroxy-tyramine hydrochloric acid (428 mg, 2.26 mmol) and N-methyl-morpholine (372 ⁇ l). ) in DMF (5 ml). The mixture was stirred under a nitrogen atmosphere for 6 hours. Water (50 ml) was added and the white precipitate formed was filtered and washed with water (10 ml) and acetone (10 ml). Recrystallization from acetone (160 ml) at -20 ° C. gave 870 mg of white powder.
- VASE Variable Angle Spectroscopic Ellipsometry
- the different substrates used are:
- Table IA Thickness measured by ellipsometry and advance contact angles with water (according to protocol A)
- Table IB Thickness measured by ellipsometry and contact angles in advance with water (according to protocol B)
- X-ray photoelectron spectroscopy (XPS) analysis shows that SuSoSl molecules are present on all surfaces by the detection of N elements. These results show that an ultra-thin layer of SuSoSl is obtained on all substrates tested. .
- a surface of gold, polished steel and ruby substrates is coated with an ultra-thin layer of SuSoS1 as described in Example 2.
- the surface appearance is excellent and there are no marks due to the deposit.
- An ultra-thin layer of Fixodrop FK-BS is coated with gold, polished steel and ruby substrates as specified by the manufacturer by dipping the substrates in a solution of tetradecafluorohexane.
- the thickness of this layer measured by ellipsometry on gold is 1.0 nm for SuSoSl and 1.7 nm for Fixodrop.
- the spreading of the lubricants on a surface is characterized by measuring the average diameter of a drop of typically 0.5 mm in diameter immediately after the drop has been deposited and after 20 minutes.
- the spread corresponds to the relative variation of the average diameter after 20 minutes.
- a good performance of a lubricant corresponds to a spread of 2% or less. Spreading greater than 10% is noticeable to the eye and is not acceptable.
- the oil used for the tests is a watch oil "941" (Moebius and Fils house, mixture of alkyl-aryl-mono-oleate and two C1 0 -C1 3 di-esters, viscosity of 110 cSt at 20 ° C, surface tension of 32.8 mN / m).
- the spread obtained is compared on surfaces of steel, ruby, aluminum, titanium dioxide and gold coated with the SuSoSl molecule, as well as a gold surface coated with the commercial product Fixodrop FK -BS of the house
- the spread is in any case lower than
- the contact angle obtained on the ultra-thin layers made with the molecule SuSoS1 is greater than 100 °, the surface energy is less than 20 mJ ⁇ f 2 , and the spread is less than 2 %.
- the layers are resistant to ruby, aluminum and titanium dioxide washings, but less well to gold and steel.
- the properties of the ultra-thin layer SuSoS1 are at least as good as those obtained with the commercial product Fixodrop.
