Polyaniline-starch blends: Synthesis, rheological, and electrical properties

The results of polyaniline (PANI) synthesis in the polysaccharide matrix were presented. Oxidative polymerization of aniline hydrochloride was conducted in solutions/pastes containing guar gum, xanthan gum, carboxymethyl cellulose, and maize starch. Ternary systems of PANI/starch/hydrocolloid were also studied. Numerous new polysaccharide-containing systems with unique rheological and electrical properties have been obtained in this study. Furthermore, it has been found that polysaccharide matrices are suitable for carrying out the oxidative polymerization reaction at ambient temperature. The obtained systems were characterized by complex viscoelastic properties, as reflected in the stress relaxation spectra gained for the fitting of the continuous Maxwell model. In addition, it has been demonstrated that the mechanism of dielectric relaxation has a very complex structure. It is confirmed by the presence of a multimodal peak in the spectra of dielectric relaxation
