摘要
Using a new method: emulsion polymerization, a novel polyurethane/acrylate (PUA) porous polymer was prepared. Compared with traditional phase inversion method, the new method can eliminate the pollution produced in process of plasticizer extraction and decrease the cost of production. The porous polymers were immerged in l mol. kg(-1) solution of LiClO4/PC to form polymer electrolytes. The structures of porous polymers and porous polymer electrolytes were observed with SEM. The conductivity of the polymer electrolytes was found to be as high as 10(-3) S cm(-1) which could be useful in many practical electrochemical devices. At the same time, the conductive mechanism of porous gel electrolytes with different liquid content was discussed. (C) 2003 Elsevier Science B.V. All rights reserved.
