Claims10
A method of preparing a self-decontaminating surface on a substrate, said method comprising:
- (1) disposing onto a substrate an aqueous mixture of an organosilane of structure (5),
- wherein R3 is alkyl;
- R5 is selected from the group consisting of alkyl and oxyalkyl;
- R6, R7, and R8 are selected from the group consisting of alkyl, alkenyl, phenyl, and benzyl;
- and X− is selected from the group consisting of chlorine, bromine, and iodine;
- and
- (2) casting a liquid coating composition comprising titanium (IV) isopropoxide over said organosilane to produce said self-decontaminating surface.
