Abstract

See full text

Fluorine-containing nano composite particles comprising a condensate of a fluorine-containing alcohol represented by the general formula:

description='In-line Formulae' end='lead'RF-A-OH  [I]description='In-line Formulae' end='tail'

wherein RF 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, or fluorine-containing nano composite particles comprising a condensate of a fluorine-containing alcohol represented by the general formula:

description='In-line Formulae' end='lead'RF′-A-OH  [Ia]description='In-line Formulae' end='tail'

or the general formula:

description='In-line Formulae' end='lead'HO-A-RF″-A-OH  [Ib]description='In-line Formulae' end='tail'

wherein RF′ is a linear or branched perfluoroalkyl group containing an O, S, or N atom, RF″ 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.
