摘要： 某些聚合物经特殊加工可制成具有半导体、导体,甚至超导体性质的材料。最近高分子固体电解质材料引起科学家们极大的兴趣和重视,其研究主要集中在聚醚体系,对聚酯研究甚少。本文对聚丁二酸丁二醇酯体系作了研究。

Abstract: The properties and structures of the complexes formed by poly (tetramethylene succinate) and various inorganic alkali metal salts are investigated in the present article. The solubility of a salt in the polyester concerns its lattice energy and melting point. The higher the lattice energy and melting point of a salt, the lower the solubility of the salt in the polymer. The properties and dissolution ability of a salt can affect the conductivity of the electrolyte. The less the size and the more the number of ions, the higher the conductivity. The conductivity of the electrolytes is mainly related with the electric conduction in the amorphous regions of the polymer. The conductive behavior of the complexes could not be described by Arrhenius equation based on the classical theory or WLFequation on free volume theory.
