摘要
系统地阐述了近几年来超细二氧化硅的制备与表面改性技术的最新进展,比较了各种方法的优缺点,并对二氧化硅的制备与改性的前景做了展望。
Ultrafine silica is an important industrial chemical, which is widely used in many fields,such as catalyst supports, macromolecular composite materials,ceramics,rubbers,fillers,paints and so on.However,the surface of silica is hydrophilic, which is not compatible with organic materials,so the silica must be surface_modified before it can be used into industrial products.The recent techniques of preparation and modification of ultrafine silica are summarized and compared.Also the research directions in future of this subject are suggested,which have a reference value to relative fields.
