Abstract
The invention relates to a curable coating composition comprising a nanoparticle-polymer composition and, optionally, superamphiphobic nanoparticles. The nanoparticle-polymer composition comprises the reaction product of an epoxy resin, a hydroxy-terminated poly(dimethylsiloxane), and a silane coupling agent, and a hybrid nanofiller. The superamphiphobic nanoparticles comprises the reaction product of silicon dioxide nanoparticles and 1H,1H,2H,2H-perfluorodecyltrichlorosilane and/or 1H,1H,2H,2H-perfluorododecyltrichlorosilane (FDDTS). The invention further relates to a cured coating composition of the invention, objects coated with the curable coating composition of the invention, methods for making the curable coating composition of the invention, and the use of the curable coating composition of the invention to coat substrates.
