摘要: Spectrophotometric, morphologic and dielectric properties of polyacrylonitrile (PAN) composite films in the presence pyrrole derivatives were reported this paper. The fabricated by oxidative polymerization (Py), N-methyl (NMPy) N-phenyl (NPhPy) cerium(IV) on matrix. effect temperature was studied frequency range from 0.05 Hz up to 10 MHz 0 °C 250 °C. Conductivity increased with due increase mobility charge carriers films. By increasing temperature, dipoles become free respond applied electric field structure; thus, polarization constant increases. PNPhPy-PAN exhibited highest constant, AC conductivity tan delta.
