马来酸酐-醋酸乙烯酯梳状聚合物单阳离子导体的制备及表征
摘要:
马来酸酐-醋酸乙烯酯交替共聚物以聚乙二醇单醚醇解,得到带有不同长度的聚醚氧侧链的羧酸型梳状聚合物,其碱金属盐在加入适当增塑剂成膜后,可作为聚合物单阳离子导体,其结构以非晶态为主,具有较低的玻璃化转变温度及较好的热稳定性,增塑后的室温电导率最高可达10-5S/cm.研究发现,适当增加侧链的长度有利于提高聚合物膜的离子电导率.此外,还详细探讨了增塑剂、阳离子半径、温度及外加频率等因素对电导率的影响.

Preparation and Characterization of Poly (Maleic Anhydride-co-Vinyl Acetate) Comblike Single-Cation Polymer Conductors
Abstract:
The comblike polymers with carboxylate groups and poly(ethylene oxide) side chains have been synthesized by alcoholysis of maleic anhydride-vinyl acetate copolymers with PEO monoether. The plasticized alkali polymer salt films showed conductivity up to 10-5 S/cm at room temperature. It was found that the conductivity increased when the length of the side chains increased appropriately. The effects of plasticizer, cation radius, temperature and frequency on the conductivity were also investigated.
