ABSTRACT
398The structure and physical chemical properties of the synthesized polymer–inorganic composites by intercalation type based on polyaniline (PAn)/copolymers of aniline and nitroaniline with xerogel of vanadium pentaoxide have been investigated. The methods of IR-spectroscopy, X-rays diffraction, and the elementary analysis were used to elucidate the structure and the composition of intercalates. The kinetics of polycondensation of anilines by oxidation of their gels was investigated by the method of differential scanning calorimetry. It was found that the rate of the oxidative copolycondensation in the presence of xerogel depends on the composition of the reacting mix due to the different reactivity of the nitroaniline isomers to copolycondensation reaction with aniline. It is shown that the thermolysis of synthesized polymer–inorganic composites at temperatures above 300 °C has a character of the oxidative degradation as a result of the vanadium (V) oxide composite component action.
The electrical conductivity of synthesized composites was studied and they were tested as cathode materials of lithium chemical power sources. It was shown that the use of copolymers of aniline with its nitro-derivatives improves the electrical characteristics of lithium chemical power sources based on hybrid polymer–xerogel composites by introducing of the electroactive nitro-groups into the structure of the polymer.
