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.
