Choice of technological conditions for synthesis of sensing materials based on polyacrylonitrile on flexible substrates

Abstract

Abstract. Cd-containing PAN films with modifying additive CdCl2 have been fabricated by pyrolysis under the influence of incoherent infrared radiation under low vacuum conditions using different temperature and time of heat treatment. The influence of modifying additive concentration and of technological conditions on the films electrical and gas sensitive properties have been investigated. AFM-investigation of the films surface morphology has been fulfilled. The technological conditions for the formation process of the sensitive layer material for hydrogen sulphide sensor have been revealed experimentally.
