摘要
SiO2 porous thin films were prepared using polyvinyl alcohol as a template. Trimethylchlorosilane (TMCS) was used as modification reagent. The effects of TMCS concentration and modification time on dielectric property and morphology were investigated. The dielectric constant and loss of the SiO 2 porous thin films decreased with the increases of modification time and TMCS concentration. When the concentration of used TMCS and modification time are 60% and 2 hours, the dielectric constant of porous silica can be lowered to 1.86. AFM analysis shows that the silica films before and after modification possess similar microstructure.
