Fluorine-containing nano-silica composite particles comprising a condensate of a fluorine-containing alcohol represented by the general formula:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒR F -A-OH€ƒ€ƒ€ƒ€ƒ€ƒ[I]
wherein R F is a perfluoroalkyl group or a polyfluoroalkyl group in which some of the fluorine atoms of the perfluoroalkyl group are replaced by hydrogen atoms, and A is an alkylene group having 1 to 6 carbon atoms; and an alkoxysilane with nano-silica particles,
or fluorine-containing nano-silica composite particles comprising a condensate of a fluorine-containing alcohol represented by the general formula:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒR F '-A-OH€ƒ€ƒ€ƒ€ƒ€ƒ[Ia]
or the general formula:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒHO-A-R F "-A-OH€ƒ€ƒ€ƒ€ƒ€ƒ[Ib]
wherein R F ' is a linear or branched perfluoroalkyl group containing an O, S, or N atom, R F " is a linear or branched perfluoroalkylene group containing an O, S, or N atom, and A is an alkylene group having 1 to 6 carbon atoms; and an alkoxysilane with nano-silica particles. |
