MECHANOCHEMICAL SYNTHESIS OF THE METYLHYDROXYETHYLCELLULOSE/POLYANILINE COMPOSITES

Abstract
The cellulose/polyaniline composites has been produced by mechanochemical (solid-phase) synthesis. The synthesized samples correspond to characteristics of composite materials. It is determined that the structure of composites is amorphous. Due to the presence of methylhydroxyethylcellulose, which is soluble partially in water, the part of the composites is a water-soluble fraction, while the other part is a disperse powder. The thermal decomposition of composites in the air atmosphere occurs in three stages, which correspond to the evaluations of water and dopant, thermooxidative destruction of polyaniline and methyl¬hydroxy¬ethylcellulose and products of their destruction, respectively. Thermal stability of composites is the same: it does not depend on the content of cellulose and corresponds to the thermal stability of pure polyaniline. All synthesized composites have electrical conductivity. An analysis of the results indicate that the nano- and microparticles of polyaniline are encapsulated in a methylhydroxyethylcellulose shell which forms during washing of the samples with water.
