摘　　要：采用常规方式制备气凝胶时,繁琐的溶剂交换和严格的干燥条件对气凝胶的应用推广十分不利。本文综述了在乳液体系中制备二氧化硅微球的研究现状,制备方法具有操作便捷、成本低廉、时间缩短等优势,乳液各组分的比例会影响其微观结构,二氧化硅微球的粒径在一定程度上可控。When the erogels were prepared by conventional methods,the cumbersome solvent exchange and strict drying conditions were very unfavorable for their application and popularization.In this paper,the present situation of preparing silica microspheres in emulsion system was described,the methods had the advantages of convenient operation,low cost and short time.The proportion of each component in emulsion could affect its microstructure,the particle size of silica microspheres could be controlled to a certain extent.
