摘要

用聚乙二醇(PEG1500) 和甲醇先后与共聚物(P(MMA-MAh)) 发生酯化反应, 合成得到交联聚合物P(MMA-MAh)-PEG1500. 以该交联聚合物P(MMA-MAh)-PEG1500、碳酸丙烯酯(PC)和锂盐(LiClO4)为三种组分制备凝胶聚合物电解质, 电解质性能必会受到这些组分间存在的微观相互作用的影响. 采用FTIR 来研究PC 和P(MMA-MAh)-PEG1500 中存在的极性基团(C＝O 和C—O—C)与Li+的相互作用. 对于PC/LiClO4 和polymer/LiClO4体系, FTIR 定量分析显示, 极性基团对Li+的吸收系数分别为0.113 和0.267, 说明在红外光谱中Li+键合C＝O 和C—O—C 极性基团比自由极性基团吸收灵敏度高; 另外, 计算该二体系中Li+键合极性基团(C＝O 和C—O—C)的当量百分数极限值分别为94%和45%, 表明极性基团与Li+间存在的相互作用是可逆的, 并且体系PC/LiClO4 中相互作用强度大于体系polymer/LiClO4.

Abstract

The crosslinked polymer of P(MMA-MAh)-PEG1500 was synthesized by reacting polyethylene glycol (PEG1500) with the copolymer of poly(methyl metacrylate-maleic anhydride) (P(MMA-MAh)) and endcapping the residual carboxylic acid with methanol. The properties of gel polymer electrolyte (GPE), consisted of P(MMA-MAh)-PEG1500 used as polymer matrix, propylene carbonate (PC) as a plasticizer and LiClO4 as lithium ion producer, was undoubtedly depended on the micro interaction existed in the components. Characterization of interaction of the polar group (C＝O and C—O—C) in PC or crosslinked polymer with Li+ has been thoroughly examined using FTIR. The quantitative analysis of FTIR showed that the absorptivity coefficient (a) of PC/LiClO4 and polymer/LiClO4 was 0.113 and 0.267, respectively, which meant that the Li+ bonded polar group of C＝O and C—O—C was more sensitive than free C＝O and C—O—C in FTIR spectra. The limit value of bonded C＝O and C—O—C equivalent fraction of PC/LiClO4 and polymer/LiClO4 was 94% and 45%, respectively, which implied that the interaction within the components was reversible and the intensity of interaction was ordered as PC/LiClO4 and polymer/LiClO4.
