摘　　要：硅源作为溶胶-凝胶法制备二氧化硅气凝胶前驱体的重要组成部分,对获得结构完整、性能优良的二氧化硅气凝胶以及构建满足不同应用需求的二氧化硅气凝胶至关重要。考察了制备二氧化硅气凝胶所用的单一硅源、复合硅源以及功能性硅源对气凝胶的形貌及物理性能的影响,并对3类不同硅源制备二氧化硅气凝胶进行了综述。Silica resource is the important part of the precursor of sol-gel method,which is the crucial one for obtaining intact construction and excellent property of the silica aerogel,meanwhile for constructing approved and required application of the silica aerogel.The effect on the morphology and physical property of the silica aerogels which using different silica resource to prepare was investigated,and the preparation of silica aerogels by three different silica resource was summed up.The silica resources include the single silica resources,compound silica resources and functional silica resources,respectively.
