  Polymeric ionic liquids based on ether functionalized ammoniums and perfluorinated sulfonimides

  摘要：

  A new family of polymeric ionic liquids (PILs) based on alkyl and alkyl ether substituted ammoniums and perfluorinated sulfonimides (i.e., bis(fluorosulfonyl)imide (FSI-), and bis(trifluoromethanesulfonyl)imide (TFSI-)) have been synthesized by polymerization of the corresponding ionic liquid monomers (ILMs). Their structures and compositions have been characterized by H-1 and F-19 NMR, FTIR and viscosity-average molecular weight (M-v). The physicochemical properties of both the ILMs and the PILs have been studied in terms of thermal stability, phase transition, and ionic conductivity. All the prepared ILMs and PILs reveal excellent thermal stabilities to greater than 250 degrees C. The PILs containing alkyl ether side unit show significant decrease in glass transition temperature (T-g), the values of T-g of the alkyl ether based-PILs are all significantly lower by 10-77 degrees C in magnitude than those of the corresponding alkyl based ones. The ionic conductivity of alkyl ether based-PILs in the best case increases up to 4.0 x 10(-6) S cm(-1) at 30 degrees C, and reaches 7.6 x 10(-5) S cm(-1) at 60 degrees C, and outperform their ammonium counterparts with alkyl side chain that were synthesized as references.

  摘要：

  一系列可聚合的四烷基铵离子液体，基于[2-(甲基丙烯酰氧基)乙基]二甲基庚基铵阳离子和双(三氟甲基磺酰基)亚胺、壬氟-1-丁烷磺酸盐、十二烷基苯磺酸盐、十七氟辛烷磺酸盐、合成了 4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,11- 十七氟十一烷酸阴离子及其相应的均聚物和共聚物，并通过 1H NMR、TG-DTA、DSC、MALDI-TOF、粘度测定法和 XPS 研究对其进行了表征。通过动态接触角和石英晶体微天平测量探究了聚（离子液体）的疏水和二氧化碳感应特性。本聚合物的二氧化碳传感行为非常显著，其特点是反应极其迅速且完全可逆，没有任何记忆效应。就灵敏度而言，[2-（甲基丙烯酰氧基）乙基]二甲基庚基铵非氟-1-丁烷磺酸盐均聚物的结果最好。张力数据显示，除了涉及 4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,11-heptadafluoroundecanoate 阴离子的聚合物（θadv = 78.3°）；代表聚合物表面最亲水部分的后退接触角在 22-54° 之间，可通过选择适当的长链 N-烷基进一步改善。
