| 中文摘要: |
| 聚苯并咪唑是一类重复基元含苯并咪唑结构的芳香杂环聚合物,具有耐高温、耐腐蚀、高机械强度、高阻燃性等特点,被广泛应用于耐高温质子交换膜、防火阻燃及航空航天领域。近年来,各种不同结构的新型聚苯并咪唑不断被合成报道,新颖的结构基元赋予聚苯并咪唑改善的溶解性、提升的抗氧化性、高的酸负载水平及多孔特性,进一步拓展了聚苯并咪唑在吸附分离及燃料电池方面的应用。综述了新型聚苯并咪唑的研究进展,重点介绍了新型聚苯并咪唑的结构种类及其功能应用,旨在促进聚苯并咪唑研究的发展。 |
| 英文摘要: |
| Polybenzimidazoles are a class of aromatic heterocyclic polymers containing the benzimidazole repeating units. On account of the characteristics of excellent thermal stability, high corrosion resistance, exceptional mechanical strength and flame retardance, polybenzimidazoles have been extensively applied in the fields of high temperature proton exchange membrane, fire retardant and aerospace. Novel polybenzimidazoles with distinct structures have been reported recently. The unique structures endow polybenzimidazoles with better solubility, enhanced oxidative resistance, higher acid doping level and porosity, which future expand the application of polybenzimidazoles in adsorption separation and fuel cells. The recent advances in the unique structures and functional applications of novel polybenzimidazoles are summarized. It’s anticipated that this review could promote the development of polybenzimidazoles. |
