Block copolymer blends have the ability to build various self-assembled nanostructures. We have studied several polymer blend systems for membrane application. A thin film of block copolymer and cyclodextrin-based polymer was prepared as active layer coating for alumina membrane. This layer was prepared by layer-by-layer processing, which the supporting membrane was alternatively dipped into the polymer solutions. The deposited layers on the supporting membrane created nano-porous structure induced by annealing and selective etching of one of the polymers in the layered coating. We expect to have controllability of nano-porosity by changing the composition, deposition and etching processes of the layer coating. This new system may have a great potential in filtration or separation membrane material development for nanofiltration or secondary battery, fuel cell technology. |
