Metal oxide surface treatment with a fluoroalkyl silanizing agent

1. A composition of matter comprising a metal oxide surface having a group (CF 3 ) 2 C(OH)—CH 2 —CH═CH—Si(O(CH 2 ) x CH 3 ) 3-Z (OM) Z where z=1, 2 or 3 bound thereto, x=0 or 1 and M is selected from the group consisting of silicon, aluminum, and titanium.

2. The composition of claim 1 wherein the metal oxide surface is a silicon oxide and M is Si.

3. A method of metal oxide surface treatment suitable for use to chemically bond organooxysilane groups onto metal oxide surfaces, the method comprising:

immersing a metal oxide surface into a solution of an organoalkoxysilane, a catalytic quantity of amine, a stoichiometric quantity of water and an inert solvent;

wherein said metal oxide surface is one selected from the group consisting of an oxide of silicon, aluminum and titanium;

wherein said organoalkoxysilane has the formula, X—Si(OR) n Z 3-n wherein X=alkyl, heteroatom functionalized alkyl and R═CH 3 , CH 2 CH 3 with n=1, 2, or 3 and Z ═CH 3 ;
