POROUS SILICA FILM-FORMING COATING HAVING EXCELLENT STORAGE STABILITY, METHOD FOR PRODUCING COATING, AND METHOD FOR PRODUCING POROUS SILICA FILM HAVING REGULARLY ARRANGED UNIFORM MESOPORE, POROUS SILICA FILM AND ITS USE

摘要

PROBLEM TO BE SOLVED: To provide a porous silica film-forming coating which excels in storage stability, a porous silica film which is produced by using the coating, has regularly arranged uniform pores and is used in optically functional materials and electronically functional materials, and a method for producing the coating.;SOLUTION: The coating for forming the porous silica film which has excellent storage stability is obtained by adding, in the presence of a surface active agent, an aprotic organic compound having a dielectric constant at 25°C of ≥25 to a reaction solution obtained by partially subjecting alkoxysilanes to hydrolysis and dehydration condensation.;COPYRIGHT: (C)2003,JPO
