Effects of the polymerization temperature on the structure, morphology and conductivity of polyaniline prepared with ammonium peroxodisulfate

Original language description

Polyaniline (PANI) samples were prepared by the oxidation of aniline with ammonium peroxodisulfate in a reaction vessel placed in a bath thermostated to particular temperature, Tb, from MINUS SIGN 20 oC to 40 oC. Temperature-time profiles of reaction mixtures were monitored except for the reaction at MINUS SIGN 20 oC that proceeded in the solid state. The temperature regime was found to influence the molecular structure, morphology, crystallinity and electrical conductivity of PANI. The increase in Tb results in an increased content of meanwhile unspecified structure defects in the formed PANI chains (the presence of attached self-doping groups is improbable), decreased crystallinity, toughness and compactness of PANI microparticles, and increased steepness of the temperature dependence of PANI conductivity. The PANI prepared in the solid-state polymerization at MINUS SIGN 20 oC shows, besides a rather high crystallinity, the unusually high position of the quinonoid band maximum: 643 n
