Electro‐ and photoconductive properties of the PVA/PAN‐I2 blends
Authors:Demtrio AW Soares  Alvaro AA de Queiroz
Abstract:The electrical conductivity of poly(vinylalcohol)/polyaniline‐iodine blend (PVA/PAN‐I2) prepared by solution process was investigated. The FTIR spectroscopy revealed a structural change of both shape and intensity of the polyaniline (PAN) bands after doping with iodine, indicating the formation of a charge transfer complex. The J‐V curves for pure PAN; PAN‐I2 and PVA/PAN‐I2 film obey the ohm law at lower voltages, deviate from the linear response at higher voltages and finally display the breakdown behavior. The PVA/PAN‐I2 exhibit photoconductivity by UV/visible irradiation as well as oscillations that may be attributed to a nonlinear behavior of the blend.
