Definitions
- the present invention relates to the production of a hydrophobic coating on glass using a polymer layer whose composition is adjusted to obtain good durability: hydrolytic, UV, mechanical.
- This coating can be applied to automotive glazing on the exposed side to improve visibility in rainy weather and thus improve safety.
- the hydrophobic layer is a molecular monolayer of a fluorinated silane, mainly (1 H, 1 H, 2H, 2H) perfluorodecylsilane.
- a first avenue of improvement was to develop a coating of the same type that can be applied to a windshield.
- the main problem in this case was to improve the mechanical and hydrolytic durability so as to be able to withstand the additional stresses on a windshield compared to the side windows.
- Hydrophobic treatment based on fluorinated silane molecular layer has two major drawbacks that cause sustainability problems:
- the treatment is based on a single layer of molecule (monomolecular layer); it is easy to understand that during aging, if a molecule comes off the surface, the released site is no longer functional; thus, any minor degradation of the surface (scratching, hydrolysis, etc.) induces a total loss of functionality at the level of the defect.
- the invention proposes to address the problem of the hydrophobic coating differently by developing a polymer material providing this hydrophobic functionality. Its molecular architecture is adjusted to obtain optimal properties in terms of hydrophobic functionality, ease of implementation, hydrolytic durability, stability under UV irradiation and finally mechanical stability.
- the subject of the invention is a copolymer of formula (I)
- the group R 1 is hydrophobic
- the group R 2 is crosslinkable
- n is an integer.
- the backbone of the polymer according to the invention is composed of four types of units resulting from four types of monomers:
- PMMA polymethylmethacrylate
- the functionality is present on the surface of the coating but also in its volume.
- the coating retains its hydrophobic functionality.
- the invention also relates to a glass substrate comprising a copolymer coating described above, with the interposition of a functional silane layer capable of reacting with the crosslinkable group R 2 .
- the silane function is in a known manner able to bind to the glass.
- the mechanical properties of the copolymer coating can be improved by incorporating mineral fillers.
- mineral fillers are most often silica nanoparticles. Their size is less than 50 nm in order not to make the coating diffusing optically.
- the surface of these mineral fillers can be functionalized in order to be able to react with the crosslinkable R 2 function of the copolymer.
- the invention also relates to the application of the glass substrate described above as
- a glass substrate is previously activated by Cerox polishing.
- an aqueous solution sold by the company Evonik was used, the concentration of which was adjusted to 1% by weight.
- the solution is applied to the glass by ragging, the coating is dried for 15min at 110.degree. C., and the excess is removed by rubbing the glass with a cloth soaked in isopropanol.
- the co-polymer is used
- HEMA hydroxyethyl methacrylate Mesylate: SO 2 CH 3
- This copolymer is solubilized at 3% by weight in methyl ethyl ketone, and deposited by spin-coating (2000 rpm) on the functionalized substrate.
- the coating is crosslinked in an oven at 130 ° C for 1 hour.
- the water contact angle measured on the functionalized substrate is measured at 11 °.
- the measured contact angle is 103 °.
- the measured contact angle is 105 °.
- a dispersion of silica nanoparticles in the methyl ethyl ketone could have been added to the formulation to enhance the mechanical properties.
