Kinetics of optical absorption changes in polymer gas-sensitive nanostructures

The kinetics of changes and recovery processes of the optical absorption of nanostructured films of polyaniline and binary nanostructures based on a mixture of polyorthoanisidine and polyorthotoluidine, obtained by the method of electrochemical deposition under the action of ammonia, carbon dioxide, and sodium sulfide vapors in the wide spectral range λ = 350–900 nm, were studied. The nature and trends of recovery of the optical absorption of the studied films are established. Recommendations for the use of synthesized thin film nanostructures as active 2D nanoelements for smart optical gas sensors with improved sensitivity, speed, and recovery parameters are proposed.
