摘　　要：利用烷氧基硅烷作为前驱体之一,进行溶胶-凝胶(sol-gel)反应制备无机氧化物和有机-无机杂化材料,近几十年来一直是一个研究热点。对烷氧基硅烷的sol-gel反应过程,特别是起始的水解和初步缩合过程已有较多的研究。本文综述了烷氧基硅烷的sol-gel反应机理研究的进展,并对未来发展提出了看法。Over the past decades, the preparation of inorganic and organic-inorganic hybrid materials by the sol-gel process of alkoxysilanes has continued to be an active research area. Among such researches, there has been much exploration on the sol-gel reaction kinetics, especially the hydrolysis and initial condensation processes. In this paper, the development of the study on kinetics of alkoxysilane sol-gel reaction is reviewed and the kinetic researches are briefly prospected.
