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.
