纳米结构TiO_2微孔复合膜的研制

The Preparation of Nannometer Pormertic TiO_2 Composite Membranes

本文用异丙醇钛经溶胶 -凝胶过程制得了二氧化钛粒子溶胶 ,确定成膜时的烧结温度 ,制得的膜经SEM测试具有典型的不对称结构 ,用压汞法测量孔径分布在 2 7～

In this paper,the colloidal sol were prepared by sol-gel process from hydrolysis of titanium tetra-isopropoxide.The burning temperature was defined.The membrane's pore size distribution was 2.7～11nm which characterized by mercury porosimetry.
