Claim Text:
1. A siloxane polymer solution composition, comprising: (i) a siloxane polymer A formed from an acid hydrolyzed alkoxysilane, an acid hydrolyzed organosilane, and optionally an acid hydrolyzed organofluorosilane, wherein the acid hydrolyzed organosilane and the optional acid hydrolyzed organofluorosilane are each separately prepared before combining, wherein the siloxane polymer A has the following formula: [RSi(OH) (ii) a hydrolysis acid catalyst; a polar organic solvent; and at least one of a porogen; and a template, wherein the porogen or the template are selected from the group consisting of ethylene oxide, propylene oxide, polyethylene oxides, polypropylene oxides, ethylene oxide/propylene oxide block co-polymers, polyoxyethylated polyoxypropylated glycols, fatty acid ethoxylates, ethylene glycol esters, glycerol esters, mono-di-glycerides, glycerylesters, polyethylene glycolesters, polyglycerol esters, polyglyceryl esters, polyol monoesters, polypropylene glycol esters, polyoxyalkylene glycol esters, polyoxyalkylene propylene glycol esters, polyoxyalkylene polyol esters, polyoxyalkylene glyceride esters, polyoxyalkylene fatty acid, sorbitan esters, sorbitan fatty acid esters, sorbitan esters, polyoxyalkylene sorbitan esters, polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan monostearate, polyoxyethylene sorbitan tristearate, and sorbitan ester ethoxylates in an amount of 0.1 to 5 wt % of total sol composition; and (iii) optionally, one or more of the following: a basic Si—OH condensation catalyst; and a surfactant.
