Abstract
The mechanic-chemical method used to produce polyvinyl alcohol (PVA) and polyaniline (PANI) composites. For synthesis, PVAs with a molecular weight of 40.0.103 and a residual amount of acetate groups of 3.2% were use. Polyaniline obtained by reaction of oxidation polycondensation of aniline with ammonium peroxydisulphate in sulfate acid medium. The thermomechanical properties of polyvinyl alcohol and composites of polyaniline from PVA been investigated. It shown that the increase in the content of PANI in the composite results in a decrease in the glass transition temperature. The conductive polymer of PANI acts on the macromolecule of PVA, which results in a decrease in the transition temperature of the glassy state - highly elastic. Electrical conductivity of composites based on PVA and PANI was study. The growth of the content of the conductive component in the composite leads to an increase in electrical conductivity. With increasing content of PANI from zero to 70% mass electric conductivity increases by four orders of magnitude. The dependence of the conductivity of composites on temperature is investigate. The energy of activation of charge transfer is find.
