用直接酯化缩聚法合成了共聚醚酯,又用熔融和溶解两种方法成膜制备了共聚醚酯(PEE)无机盐复合物,并测定了它们的体积电阻率。结果表明,含有聚乙二醇(PEG)柔性链段、同时添加第三单体的共聚醚酯和无机盐的复合物,具有较低的玻璃化温度,从而体积电阻率较低。体积电阻率的测定结果还表明,溶解成膜的体积电阻率比熔融成膜的低。电镜照片说明,溶解成膜的结构比熔融成膜的规整,微相分离有序且完全,因此更能发挥聚醚段的作用。红外分析表明,无机盐金属阳离子(Li+)主要与柔性链段的醚氧原子配位。
Copolyetherester was synthesized by direct esterification polycondensation method, and copolyetherester (PEE) inorganic salt complex was formed by melt and solution method. Their volume resistivity was measured. The results show that the complex containing poly (ethylene glycol) (PEG) soft segments with the addition of the third monomer copolyetherester and inorganic salts has lower glass transition temperature and hence lower volume resistivity. The results of the volume resistivity measurement also showed that the volume resistivity of the solution deposited film was lower than that of the melt film. Electron microscopy images show that the structure of the solution-forming film is more orderly and completely separated than the melt-filming and the micro-phase separation. Therefore, the effect of the polyether segment can be further exerted. Infrared analysis shows that inorganic metal cation (Li +) is mainly coordinated with the ether oxygen atoms of the soft segment.
