Gas-sensing elements based on Ag-containing polyacrylonitrile (PAN) films using different temperature and time modes of a two stage IR-pyrolysis have been fabricated. It has been investigated that the gas sensitivity of the samples depends on the composition of the original film-forming solution and on the process parameters of forming the film material. It has been studied that the samples demonstrate gas-sensing properties to Cl2 at room temperature. The outcome of this study is that Ag-containing PAN films can be considered as one of the most promising material to be used in electronic engineering.

The cobalt-containing polyacrylonitrile (PAN) films were fabricated using IR-pyrolysis under low vacuum conditions. It was found that Co/PAN films have a porous structure and cobalt nanoparticles with size 0.1-0.2 μm embedded into PAN matrix. Besides, as a result of interaction between PAN matrix and Co ions unsaturation in the polymer backbone is observed caused by the transformation of the C≡N triple bond to a C=N double bond. At the same time formation of Co-N bond is observed.

The calculations of the dimer, trimer and tetramer molecules of polyacrylonitrile (PAN) using the quantum-chemical method are carried out. The computer simulation of formation of a polymer PAN chain by the Monte-Carlo method taken with the Metropolis and Wang-Landau algorithm is done. Technology of fabrication of gas-sensing material based on metal-containing PAN is developed. Electroconductive metal-containing PAN films are fabricated by method of pyrolysis under the influence of incoherent IR-radiation. Their sensing properties are studied.
