Abstract
The metal-containing (Cu, Co, Ag, Cr) polyacrylonitrile (PAN) thin films were fabricated using IR-pyrolysis under low vacuum conditions in different temperature and time modes. The thickness of the fabricated films was between 0.01÷0.68 μm. The metal-containing PAN films had the resistance values in the range from 2.9·102 to 5.1·1011 Ohm. It has been investigated that the film thickness, resistance and gas sensitivity of the samples depends on the composition of the initial solution and on the process parameters of the film material's fabrication. It has been studied that the samples demonstrate gas-sensing properties to CO, NO2, Cl2 and gasoline vapours at room temperature.
