SUBSTRATE FOR POLYMER BRUSH FORMATION, PRODUCTION METHOD FOR SUBSTRATE FOR POLYMER BRUSH FORMATION, AND PRECURSOR LIQUID FOR USE IN PRODUCTION METHOD FOR SUBSTRATE FOR POLYMER BRUSH FORMATION

摘要

The purpose of the present invention is to provide a surface treatment technology that makes it possible to give excellent surface functionality to surfaces of a variety of large-area substrate materials. According to the present invention, when precursor solution containing an organosilane and a metal alkoxide is coated on a substrate material to form a polymerization initiator layer by a sol-gel process, a polymerization initiator group-containing organosilane having a formula: X-R1-(Ph)k-(R2)m-Si-R3nR43-n(X stands for a halogen atom, R1stands for an alkylene group having 1 to 3 carbon atoms, Ph stands for a phenylene group, R2stands for a C1 to C10 alkylene group optionally via an oxygen atom, R3stands for an alkoxy or chloro group having 1 to 3 carbon atoms, R4stands for an alkyl group having 1 to 6 carbon atoms, k is 0 or 1, m is 0 or 1, and n is 1, 2 or 3) is used as the organosilane.
