1 Results Micro-porous polymer electrolytes(MPEs), which almost obtained by the conventional methods of phase inversion process or immersion precipitation method, have significant advantages such as high ionic conductivity and excellent mechanical properties[1].In our work, micro-porous structure is obtained by adding SnO2 nanorods usually used as gas senor materials into the polymer matrix, which proves a new way to prepare MPEs.SnO2 nanorods were synthesized by microemulsion hydrothermal method[2]. Then micro-porous polymer electrolytes was prepared by in-situ copolymerization of P(MMA-AN) on the surface of the SnO2 nanorods. Scanning electron micrographs (Fig.1) show this polymer electrolyte containing several micro-porouses with the diameter of 200-500 nm.
