Title:
Dispersion liquid of fluorine-containing nano silica composite particles
Document Type and Number:
Japanese Patent JP5996056
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a dispersion liquid of fluorine-containing nano-silica composite particles having excellent water- and oil-repellency and, using a fluorine-containing alcohol which does not produce perfluorooctanoic acid or the like even when released into the environment in the case of a perfluoroalkyl group having less than 8 carbon atoms.SOLUTION: A dispersion is obtained by dispersing, in a non-fluorine-based polar solvent, fluorine-containing nano-silica composite particles comprising a condensate of a fluorine-containing alcohol represented by the general formula R-A-OH (where Ris a perfluoroalkyl group and A is an alkylene group) and an alkoxysilane with nano-silica particles.
