摘　　要：以硅树脂和硅凝胶为原料，制备出一种多孔性的、一体化硅基复合膜．这种硅基复合膜的气体（对H2）渗透率为105～106Barrer，其H2／N2分离因子为3～4.13;Q2／N2分离因子为1～1．29．经过表面处理的硅基复合膜，其H2／N2最大可达16．15;OZ／N2可达5．32．这种复合膜适用于热工业气体的分离．A porous, integral silicon-based composite membrane was developed, with silicon gel and silicon resin as raw materials. Its gas permeability for H2 is about 105~106 Barrer; and its separation factor for H2/N2 is 3~4.13, for O2/N2 is 1~1.29. The selectivity of the membrane is improved through surface treatment,upon which the separation factor reaches 16.5 for H2/N2 and 5.32 for O2/N2. The composite membrane is suitable for hot industral gas separation in an oxidizing environment.
