摘要

ABSTRACT > Film‐forming polymers containing ionic groups have attracted considerable attention as emerging materials for gas separation applications. The aim of this article was to synthesize new film‐forming polyimides containing imidazolium groups (PI‐IMs) and establish their structure–performance relationship. In this context, a new aromatic diamine, namely, N 1 ‐(4‐aminophenyl)‐N 1 ‐(4‐(2‐phenyl‐1H‐imidazol‐1‐yl)phenyl)benzene‐1,4‐diamine (ImTPADA), was synthesized and polycondensed with three aromatic dianhydrides, namely, 4,4′‐(hexafluoroisopropylidene)diphthalic anhydride, 4,4‐(4,4‐isopropylidenediphenoxy) bis(phthalic anhydride), and 4,4′‐oxydiphthalic anhydride to form the corresponding polyimides containing pendent 2‐phenylimidazole groups (PI‐IEs). Next, PI‐IMs were prepared by N ‐quaternization of pendent 2‐phenylimidazole groups present in PI‐6FDA using methyl iodide followed by anion exchange with bis(trifluoromethane)sulfonimide lithium salt (LiTf <sub>2</sub> N). PI‐IEs and PI‐IMs exhibited reasonably high molecular weights, amorphous nature, good solubility, and could be cast into self‐standing films from their DMAc solutions. Thermogravimetric analysis showed that 10% weight loss temperature of PI‐IEs and PI‐IMs were in the range 545–475?°C and 303–306?°C, respectively. Gas permeability analysis of films of PI‐IEs and PI‐IMs was investigated by variable‐volume method and it was observed that incorporation of ionic groups into PI‐6FDA resulted in increased permeability while maintaining selectivity. In particular, polymer bearing Tf <sub>2</sub> N ? anion exhibited high CO <sub>2</sub> permeability (33.3 Barr) and high selectiv </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><abstract xmlns =“http://www.wiley.com/namespaces/wiley”type =“main”> <title type =“main”>含有离子基团的成膜聚合物吸引广泛的关注作为气体分离应用的新兴材料。本文的目的是合成含有咪唑鎓基团（PI-IMS）的新成膜聚酰亚胺并建立其结构性能关系。在这种情况下，一种新的芳族二胺，即N 1 </ sup> - （4-氨基苯基）-N 1-（4-（2-苯基-1h-咪唑-1 - 苯基）苯-1,4-二胺（IMTPADA）被合成并用三种芳族二酐，即4,4' - （六氟异丙基）二苯二甲酸酐，4,4-（4,4-异丙基噻苯氧基）BIS （邻苯二甲酸酐）和4,4'-氧的酸酐，形成含有沉积2-苯基咪唑基（PI-IES）的相应聚酰亚胺。接下来，通过使用甲基碘的PI-6FDA中存在的侧链2-苯基咪唑基团的Quaternizate，然后使用双阴离子交换（三氟甲烷）磺酰亚胺锂盐（Litf <sub> 2 </ sub> n）。 PI-IES和PI-IMS表现出相当高的分子量，无定形性，良好的溶解度，并且可以从其DMAC溶液中浇铸到自我站立膜中。热重分析表明，PI-IES和PI-IM的10％重量损失温度分别为545-475°C和303-306Ω°C。通过可变体积法研究了PI-IES和PI-IMS膜的透气性分析，观察到将离子基团掺入PI-6FDA中，导致渗透性增加，同时保持选择性。特别地，聚合物轴承TF <sub> 2 </ sub> n 阴离子显示出高CO <sub> 2 </ sub>渗透率（33.3bar）和高选择 </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-35621/'>《Journal of Polymer Science, Part A.
