Abstract:
A process for treating a silica film on a substrate, which comprises reacting a suitable hydrophilic silica film with an effective concentration of a multifunctional surface modification agent, wherein said silica film is present on a substrate and wherein said reaction is conducted under suitable conditions and for a period of time sufficient for said surface modification agent to produce a treated silica film that is substantially hydrophobic, wherein said surface modification agent is a compound having a formula selected from the group consisting of R1Si(NR2R3)3; R1Si(ON&boxH;CR2R3)3; and (R1)xSi(OCOR2)y and combinations thereof, wherein R1, R2 and R3 are independently H, alkyl, aryl, and x is an integer ranging in value from 1 to 2, and y is an integer ranging in value from 2 to about 3, and x and y are the same or different.
