摘　　要：将含有氨基的硅烷偶联剂3-氨丙基三乙氧基硅烷(APTES)接枝在多孔Si O_2片上,得到氨基活化的多孔Si O_2基底Si O_2/APTES。以氨基活化的多孔Si O_2为基底制备大面积连续致密的无机膜三乙烯二胺对苯二酸合锌(Zn_2BDC_2DABCO),即Si O_2/APTES/Zn_2BDC_2DABCO复合膜。通过傅里叶红外光谱(FTIR)、X-射线衍射(XRD)、扫描电镜(SEM)、气体分离测试对得到的复合膜的化学结构、表面形貌和气体分离性能等进行了表征分析。结果表明:制备的复合膜具有与模拟的立方体结构具有一致的晶相,且无机膜连续致密,无缺陷;气体分离测试结果显示该无机膜对CO_2具有很好的选择性,可以用来分离和回收CO_2。Amino activated porous Si O2substrates（Si O2/APTES）have been synthesized by grafting the amino group on porous Si O2sheet.The triethylenediamine Zinc Terephthalate composite film（Zn2BDC2DABCO）,a large area continuous and dense inorganic film,was prepared by Si O2/APTES.The chemical composition,surface morphology,and gas separation performance of the composite films were characterized by Fourier transform infrared spectroscope（FTIR）,X-ray diffraction（XRD）,scanning electron microscopy（SEM）and gas separation.The results show that the prepared composite film has the same crystal phase as the simulated cubic structure,and the inorganic film is continuous and compact without defects.In addition,the inorganic film has a good selectivity of CO2,it can be used to Separate and recycle CO2.
