The methods of formation of the free standing flexible gas sensitive films from the composites of conjugated polyaminoarenes (polyaniline, polyorthoanisidine, polyorthotoluidine) with dielectric polymer matrices (polyvinyl alcohol, polyacrylic or polymethacrylic acids) were developed. Synthesis of composites was carried out by “in situ” polymerization of monomers inside the polymer matrix by chemical oxidative polymerization. It has been established that the presence of dielectric matrices in flexible composite films does not alter the nature of optical absorption of polyaminoarenes and provides the possibility of using of the synthesized composites to produce gas sensors. For practical application the optimal are the structures based on the flexible sensor films which change their color under action of gases and may be used as visual indicators of ammonia in the food industry and in environment.
