PVDF-LiClO_4高分子快离子导体膜的制备工艺研究

STUDY ON THE PREPARING TECHNOLOGY OF THE FILM OF PVDFLiClO4 POLYMERIC SOLID ELECTROLYTES

制得了室温离子电导率达６．９４×１０－４Ｓ＼ｃｍ的聚偏氟乙烯－高氯酸锂高分子快离子导体膜，考察了载流子的浓度、添加剂的性质、用量及膜亚微观结构形态、凝聚态性能对其电导率的影响，初步探讨了不同情况下载流子的传导机理，表明了以聚偏氟乙烯为载流子传导基质可望获得性能良好的高分子快离子导体膜。

 film of polyvinylidene fluoride (PVDF)LiClO4 polymeric solid electrolytes (SPE) which conductivity exhibits of 6.94×10-4 S cm at ambient temperature has been acquired. By investigating the effect of the concentration of carries, amount and property of additive, temperature, submicromorphology of the film on the conductivity of the film, the results show a excellent SPE film desirable acquired by using PVDF as the carries conducting matrix.
