Abstract
A coating composition comprises a functionalized epoxy resin and a fluoroalkyl-modified particle, such as activated carbon or silica. The functionalized epoxy resin is a ternary polymer composition comprising one or more epoxy resin moieties linked to a polyethylene backbone through an oxygen atom, fluoroalkyl(poly)propionyl groups being grafted to the polyethylene backbone. The coating compositions have superhydrophobic properties useful for self-cleaning surfaces and bubble release from sensors.
Claims22
A coating composition comprising:
- (a) a ternary polymer composition comprising
- (i) a fluoropolymer comprising a polyethylene backbone optionally containing one or more double bonds, the polyethylene backbone being substituted with a plurality of fluoro groups and optionally a plurality of oxygen atoms;
- (ii) a plurality of fluoroalkyl(poly)propionyl groups grafted to the polyethylene backbone;
- and
- (iii) one or more epoxy resin moieties linked to the polyethylene backbone through an oxygen atom;
- and
- (b) a fluoroalkyl-modified particle.
A coating composition prepared by reacting a dehydrofluorinated polyvinylidene fluoride polymer with a fluoroalkylacrylate, a radical initiator, an epoxy resin, and a fluoroalkyl-modified particle.
