将铝交联膨润土与有机溶剂溶解的EVA混合制备导水复合涂层, 测定了纤维在不同温度下的连续失水情况、交联剂对膨润土的修饰效果和材料的孔结构. 结果表明, 铝离子水解产生多种聚合度交联剂, 膨润土经其修饰后层间由单一的规则孔道变为多种杂化孔道, 最小孔道是一种尺寸为1.5 nm的板状毛细孔, 增大了比表面积, 提高了吸附性能. 这种结构产生的毛细孔凝聚能实现对水的有效控释.
Carbon pillared inorganic porous material were prepared by bentonite with the addition of Al3+ cross-linking agent. Al3+ cross-linking agent polish bentonite as Hydraulic conductivity Coating material，s hydraulic conductivity properties was researched, The porous material were characterized by the FT-IR spectrum, XRD, and nitrogen absorption. The influence of cross-linking agent was investigated respectively. The research results show that surfactant combine with bentonite particles by both types of covalent bond and particles embedded, material，s average pore size is of nano and comparing surface very large, polished bentonite has great adsorption and is of good watering property as hydraulic conductivity coating.
