室温一步法合成的交联聚醚高分子固体电解质薄膜

A CROSSLINKED POLYEIHER SOLID ELECTROLYTE FILM MADE BY ONE-STEP REACTION AT ROOM TEMPERATURE

用室温一步法由2000左右分子量的聚乙二醇衍生物和多官能异氰酸酯PAPl合成了交联聚硅类高分子固体电解质薄膜。该种薄膜厚度在100μ左右,室温离子电导率为10^(-5)S/cm数量级,且具有较好的尺寸稳定性。若加入丙烯碳酸酯或N-甲基乙玖胺作添加剂,可使该种高分子固体电解质薄膜的室温离子电导率达10^(-4)S/cm以上。

By one-step reaction of polyethylene glycol derivative (M. W. -2000), multy-functional isocyanate PAP1 as crosslinking reagent, lithium salt solution, or additive at room temperature, a crosslinked polyether solid electrolyte film is synthesized. The film with about 100μthickness has good toughness and dimentional stability. Its conductivity is 10-5 S/cm at ambient temperature. Their conductivity is going to reach 10-4 S/cm order of magnitude or higher if some additive, for example PC or N-methl acetimade, is added.
