Nanoscopic particle-doped polymer membrane prepared by the counter diffusion method and its properties

摘要

A nanometer-size particle-doped membrane has been prepared by a counter diffusion method. It was obtained by inserting a finely porous gel membrane between solutions of different reactants. The resultant membrane looks like a solid solution. The particle size is primarily determined by the extent of the gel network of the supporting gel membrane. The particle content in the membrane is in the range 3-20 wt% and the particle size is in the range 3-20 nm. Some membrane properties have been examined.
