The influence of different substrates on charge state of thin polymer films of P(VDF + TeFE) and polystyrene is investigated. By methods of IR spectroscopy, TSD and atomic-force microscopy (AFM) is established, that substrate surface changes supermolecular structure and molecular mobility of macromolecules, influences significantly on physical structure, charge state of films, on features of sta- bilization of electret charges in them. This influence is determined mainly with surface energy of sub- strate material. The correlation between surface energy, density of films, and also surface electret charge is determined.
