Abstract

Poly(arylene ether nitriles)/copper phthalocyanine (PEN/CuPc) functional nanohybrid films with high dielectric permittivity (140 at 100 Hz) were prepared by a solution-casting method. These films can be employed with giant dielectric permittivity copper tetra-amine phthalocyanines as a functional organic filler and acid-contained poly(arylene ether nitriles) as a polymer matrix. Dielectric properties of the PEN/CuPc showed that the nanohybrid films exhibited significant increase in dielectric permittivity by adding CuPc in polymer resin. Meanwhile, dielectric loss of the films was drastically decreased after heat treated at high temperature and the dielectric dispersion of the films became smaller. These results indicate that chemical interaction has an obvious effect on the dielectric property of the nanohybrid films.

► PEN/CuPc nanohybrid films were prepared via the solution blend method. ► These films have high dielectric permittivity about 140 at 100 Hz. ► Dielectric properties of films were changed after heat treatment. ► Morphologies of films changed owing to the chemical interaction.
