增塑对UV固化型高分子固体电解质性能的影响

将合成的大分子量的聚乙二醇丙烯酸酯(PEGDA)齐聚物与光引发刑、LiClO4组成光敏体系，与一定比例的碳酸乙烯酯(EC)、碳酸丙烯酯(PC)或其混合物进行混合，经紫外光辐照制得了一种新型的高分子固体电解质膜，考察了增塑刑种类和用量对光固化速率、电导率和机械性能的影响。结果表明，增塑是提高UV固化型高分子固体电解质导电性能的有效方法，在机械性能满足使用要求的条件下，增塑的UV固化型固体电解质的电导率可以高达10^-4S／cm左右。

EFFECT OF PLASTISIZER ON THE PROPERTIES OF UV-CURABLE POLYMER SOLID ELECTROLYTES

Polyethylene glycol diacrylate(PEGDA), which contained acrylic end-groups, was prepared for solid polymer electrolytes(SPE)with a solid acid as catalyst. A novel type of SPE was obtained by mixing PEGDA with photoinitiator, LiClO 4, and plasticizer, and then being irradiated by UV light. The UV-curing, conducting and mechanical performances, depending on the type and the contend of plasticizer, were primarily discussed. The conclusion showed: plasticizing was an efficient method of improving the conductivity of UV-curable solid polymer electrolytes, and the conductivity of this kind of electrolytes was up to about 10 -4 S/cm when the mechanical performance of it was satisfying.
