Polymeric compositions with hematite nanoparticles and organic compounds with charge transfer

摘要

The magnetoresistance, electric and photoconductivity of polymeric films based on polyvinylbutyral doped with compounds with intramolecular charge transfer (CICT) and containing nanoparticles Fe2O3 have been investigated. The photoconductivity of such polymeric compositions is governed by photogeneration of non-equilibrium charge carriers from excited with light CICT molecules and by their transport inside and between the particles. Revealing of inner photoeffect in investigated nanocomposite are of interest for development of new mediums with photomagnetic properties.
