Polyacrylonitrile-derived polyconjugated ladder structures for high performance all-organic dielectric materials

Abstract

A novel all-organic polyconjugated ladder structures–polyimide (PcLS–PI) composite was successfully synthesized, in which PcLS were derived from polyacrylonitrile (PAN). The PcLS–PI composite not only presents high dielectric performances of high dielectric permittivity, low dielectric loss, high electrical breakdown strength and high energy density, but also has excellent mechanical and thermal properties.
