摘要:

耐高溫腈基聚合物是通過鄰苯二甲腈類單體在高溫下的加成聚合反應而得到的一系列高性能熱固性樹脂的統稱，因此也被稱為鄰苯二甲腈樹脂。由于其具備優異的高溫力學性能、熱（氧）穩定性、耐腐蝕性、阻燃性及良好的加工性能，鄰苯二甲腈樹脂在航空航天、船舶制造、微電子工業等高科技領域內展現出廣泛的應用前景。本文首先簡要介紹了鄰苯二甲腈樹脂的基本結構與熱聚合機理；其次重點闡述了不同結構的鄰苯二甲腈單體在固化劑作用下的熱固化行為，明確了鄰苯二甲腈樹脂結構與性能的關系；隨后分別介紹了鄰苯二甲腈樹脂的結構改性、加工性能、纖維增強復合材料的制備與性能研究、鄰苯二甲腈聚合物的電磁功能化技術途徑；最后簡要分析了耐高溫腈基聚合物及復合材料目前所面臨的技術瓶頸并探索了未來的發展方向。

Abstract:

High temperature resistant nitrile-based polymers, also named as phthalonitrile resins, are high performance thermosets obtained by the addition polymerization of phthalonitrile monomers. Due to their outstanding high temperature mechanical properties, (oxidative) thermal stability, corrosion resistance, fire resistance and good processability, phthalonitrile resins have been widely used in various high-tech fields such as aerospace, microelectronics, ship manufacture, etc. In this review article, the basic chemical structures and thermal polymerization mechanism of bisphthalonitrile resins were firstly introduced, then the thermal curing reaction of various different phthalonitrile monomers in the presence of curing agent was discussed to clarify the structure and properties of bisphthalonitrile resins.     Furthermore, the structural modification, processability, preparation and properties of fiber reinforced composites, electro-magnetic functionalization for phthalonitrile-based polymers were introduced. The review ends a brief outlook of the future directions and prospects of the research area.
