合成了一系列由聚(1-乙烯基-3-乙酸烷基酯咪唑)阳离子和二(三氟甲基磺酰亚胺)阴离子(TFSI)组成的聚离子液体并进行了表征.热重分析(TGA)和电导率分析表明,在聚(甲基丙烯酸甲酯-醋酸乙烯酯)(P(MMA-VAc))基体中掺杂聚离子液体后,体系的热稳定性和离子电导率均大为改善,红外光谱(FT-IR)、示差扫描量热分析(DSC)、X射线衍射(XRD)和扫描电子显微镜(SEM)等测试结果亦可佐证.讨论了离子液体的结构以及不同种锂盐(LiClO4,LiBF4,LiTFSI)对电解质性能的影响.由PIL/P(MMA-VAc)/LiTFSI组成的共混电解质膜,在可见光下透过率≥90%,可作为离子导电材料用于电致变色器件(ECD),显示了其优良的电化学性能.
A series of polyionic liquids consisting of poly (1-vinyl-3-alkyl-imidate) cations and bis (trifluoromethylsulfonyl) anions (TFSI) were synthesized and characterized. (TGA) and conductivity analysis showed that the thermal stability and ionic conductivity of the system were both large after the poly (ionic liquid) was doped into the matrix of PMA-VAc (P (MMA-VAc) For the improvement, the results of FT-IR, DSC, XRD and SEM are also validated.The structure of ionic liquids and the effects of different lithium (LiClO4, LiBF4, LiTFSI) on the properties of electrolytes.Phased electrolyte membranes composed of PIL / P (MMA-VAc) / LiTFSI have a transmittance of ≥90% under visible light and can be used as ion conductive materials for electricity Induced discoloration device (ECD), showing its excellent electrochemical properties.
