摘要:

20世紀80年代初，因國防軍工和尖端技術的需求而發展起來的聚芳醚腈作為一類綜合性能優異的結構型高分子材料，具有很高的耐熱性、絕緣性、耐輻射性、耐化學性、抗蠕變性及機械強度等，使其作為結構型材料、電子材料和電子元件在航空航天、電子、通信、石油開采、汽車以及其他高技術領域得到了廣泛的應用。通過分子設計及親核芳香取代反應制備的聚芳醚腈主要有聚芳醚腈均聚物、聚芳醚腈共聚物、功能性側基聚芳醚腈及交聯型聚芳醚腈四大種類。結合作者課題組之前的研究成果積累，綜述了近年來有關于新型特種工程塑料聚芳醚腈的合成、結構、性能、加工及應用等方面的研究。著重介紹了聚芳醚腈單一填料復合材料及多組分復合材料、熒光功能材料、介電功能材料等的開發，并探討了功能性側基聚芳醚腈在廢水重金屬離子吸附及作為質子交換膜在燃料電池領域的應用。文章最后對該領域的研究方向和前景作了展望。

Abstract:

Polyarylene ether nitriles (PEN) have emerged as structural polymers of excellent comprehensive properties as the increasing requirements from national defense and high-tech field since 1980s. Owing to their high thermal stability, electrical insulation, resistant to radiation and chemical corrosion, anti-creep and good mechanical properties, PENs have been widely employed in structural materials, electronic materials/devices, aerospace, telecommunication, petro exploration, automobile, etc. Basically, PENs obtained from nucleophile substitution reaction be classified as four types: PEN homopolymer, copolymer, PEN containing functional side groups and crosslinked PEN. In this article, the synthesis, structure, properties, processing and application of novel PEN developed recently in our group have been reviewed. Especially, the single-component composites, fluorescent and dielectric functional materials based on PEN and their application as heavy metal ions absorption, proton exchange membrane and fuel cells have been discussed. The review ends a brief outlook of the future directions and prospects of the research area.
