摘要
探讨了正硅酸乙酯的溶胶－凝胶过程中，氢氟酸，盐酸，氨水，硫酸和醋酸等催化剂对水解、聚合和胶凝时间的影响。催化剂可以缩短胶凝时间，醋酸与其他催化剂的催化机理不同，效果也不同。
In the sol_gel process of TEOS (tetraethoxysilane), the effects of catalysts on hydrolysis reaction,condensation reaction and gelling properties were discussed. Catalyst can shorten gelation time. But the different catalyst has the different result because of different mechanism.
