Abstract:
A process for forming a nanoporous dielectric coating on a substrate which comprises:A) performing either (i) or (ii):i) a) combining a stream of an alkoxysilane composition with a stream of a base containing catalyst composition to form a combined composition stream which is unbounded at a point of confluence; and conducting steps (b) and (c) in either order or simultaneously:b) immediately depositing the combined composition stream onto a surface of a substrate;c) exposing the combined composition to water; andii) a) combining a stream of an alkoxysilane composition with a stream of water to form a combined composition stream which is unbounded at a point of confluence; andb) immediately depositing the combined composition stream onto a surface of a substrate; andB) curing the combined composition to form said nanoporous coating.
