【 摘 要 】

An inorganic-organic hybrid system, silica-poly(ethylene glycol) sonogel is reported. This system was prepared via sol-gel method by varying various processing variales e.g. ultrasonic radiation time , gelling temperature, PEG content and its molecular weight. Various experimetal techniquewere employed to analyze the morphological, mechanical and optical properties of the system. The results were discussed in the light of existing theories. The sonogel system exhibited thecommon features of inorganic-organic hybrids. SiO2-10 wt% PEG sonogel exhibited the morphological, mechanical and optical properties superior to those reported earlier for the classic gels and found suitable for device applications,
