摘要：

Pore characteristics of silica gels prepared by the polymer-incorporated alkoxide-based sol-gel process have been investigated. Micrometer-range Pore sizes could be controlled by changing several reaction parameters, such as molecular weight or concentration of polymer or reaction temperature, that affect the domain formation process due to an occurrence of phase separation during a gel-forming reaction. The volume fraction and size distribution of nanometer-range pores after a heat treatment were varied by different solvent exchange treatments of a wet gel.
