Photoelectric effects in polymer – (CdS) – ferrocene composites

In our work, we investigated the photoelectric effects arising in composites consisting of polar (fluorine-containing) and non-polar (polyolefin) polymers—such as high-density polyethylene (HDPE), PVDF, F42 — and an inorganic phase composed of AIIBVI (CdS, ZnS) and ferrocene. In addition, the processes occurring in these composites during the creation of these effects have been studied. It was found that the parameters of the formation of the posistor effect in the polymer-ferrocene composite are related to the presence of an interphase potential barrier, which is determined by the geometric dimensions of the interphase transition layer, dielectric permeability, electric charge state, and the difference in ionization potentials of ferrocene and the transition layer. The main reason for the formation of the photoquenching effect of the rotational conductivity in polyolefin-ferrocene composites is the formation of a local electric field directed opposite to the external field as a result of the formation of multi-charged centers and dipole moments in the ferrocene phase under the influence of light.
