Abstract

The films of polymeric composites based on a copolymer of acrylonitrile with styrene (SAN) with the low concentration of an anionic (AD) and (or) cationic polymethine dye (CD) are obtained. The increase of the electroconductivity of SAN films, that contained dye additives, is detected by comparison with the electroconductivity of pure SAN films. The photoconductivity of SAN films with cationic dye additions wasn't found out on the irradiation in the visible region of light. On the contrary, the photoconductivity of the SAN films with AD addition was detected on the photoexcitation in the region of dye absorption. Some features of the photoconductivity and electroconductivity of such composites doped with AD are investigated.
