Abstract

The dielectric behavior of poly(acrylonitrile) (PAN) has been investigated through the formation of electrically polarized films. The thermally stimulated discharge spectrum of PAN reveals at least three different peaks, two of which might be related to the relaxation of oriented nitrile side groups (90 and 145 degree C). Intense current peaks observed above 160 degree C are believed to be associated with backbone mobility in amorphous and paracrystalline regions. It is suggested that nitrile orientation with an applied electric field results in the formation of a highly developed level of intermolecular bonding.
