摘　　要：以正硅酸乙酯(TEOS)和氧氯化锆(ZrOCl2·8H2O)为先驱体,乙醇为溶剂,采用溶胶-凝胶法在Al2O3基体上制备了SiO2/ZrO2无机复合膜。重点考察了锆含量、浸没时间、涂膜方式对膜性能的影响。实验结果表明:随着锆含量的增大,渗透比达到最大值时的涂膜次数减少,采用高低锆浓度结合涂膜以及适当的浸没时间可以提高膜的综合性能。By using TEOS and ZrOC12 · 8H2O as precursor and ethanol as solvent, SiO2/ZrO2 inorga- nic composite membranes on the substrate of Al2O3 system were prepared by sol-gel method. The study focused on the effect of the zirconium content, immersion time and coating method on the performance of membranes. The experimental results show that when the penetration ratio reaches a maximum the coating oumber reduces with increasing the zirconium content. The membrane coated by combined with high and low zirconium content and suitable immersion time can be of better comprehensive perfor- mance.
