“…Then, the samples were dried in oven at T = 160 ° C for 30 minutes. The temperaturetime IR-annealing regimes were selected experimentally, because the intensity and duration of exposure to IR radiation makes it possible to control the properties of the film material, changing the molecular structure of the polymer [6]. Halogen lamps KG-220 with high radiation in the area of 0.8 µm -1.2 µm were used as the source of radiation.…”

“…The technology of fabrication gas sensitive PAN films that does not require high-tech equipment and the ability to exhibit gas-sensing properties at room temperatures opens the prospect of creating flexible sensors. The gas-sensitive metal-containing PAN thin films have been fabricated [6] that are sensors for detecting to CO, NO2, Cl2, NH3, H2S [7][8][9][10].…”

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.

“…Super capacitors, solar cells, photodetectors [6], catalysis, sensors, and energy conversion and storage are just a few of its numerous uses. Awnings for the outdoors, fiber-reinforced concrete, and hot gas filtration systems have all used homo polymers of poly acrylonitrile as fibers [7]. Knitted clothing, including socks and sweaters, are frequently made using copolymers that contain polyacrylonitrile as fibers [8], in addition to outdoor goods like tents and related stuff.…”

“…In 1942, it was transformed into spun fibers and sold under the brand name Orlon [9]. Due to the presence of a high polarity group (CN) along the polymer chain, polyacrylonitrile is a versatile polymer [7]. In this study, the optical characteristics of the produced Polyacrylonitrile polymer were examined at various temperatures.…”

In this paper, a polyacrylonitrile polymer was prepared and study its optical properties with different temperatures a films clear change from light brown to very dark brown at a temperature range (25- 280⁰C), although the polymer is characterized by high transparency and analyzing the absorbance spectrum of the prepared films, the direct energy gap was calculated, which was in the range of 4.01eV for without annealing films to decrease to 1.63eV for films annealing at a temperature of 280⁰C with these changes in properties, these films can be used in optical applications such as solar cells and photodetectors.

“…Thin films of PAN that have passed infrared (IR) annealing at temperatures of 300-600 • C have semiconductor and gas sensitive properties already at room temperature [5,[7][8][9][10][11][12][13]. Such materials can be used in energy-efficient gas sensors to monitor air quality [10,11].…”

This work presents theoretical studies of the interaction of molecules of several gaseous pollutants with polyacrylonitrile (PAN) surface in the presence of a water and/or oxygen molecule. For this purpose, a PAN cluster model has been proposed by the methods of quantum chemical calculations and molecular modeling. The energy-favorable positions, in which the gas molecules are located relative to the surface of the PAN cluster, are determined and the thermodynamic and the following geometric parameters of the systems are calculated: “PAN cluster − oxygen molecule”, “PAN cluster − oxygen molecule − gas molecule”, “PAN cluster − water molecule − molecule of oxygen”, and “PAN cluster − a molecule of water − an oxygen molecule − a gas molecule”. It is concluded that PAN in atmospheric air in the presence of oxygen molecules is sensitive to carbon oxide (IV), sulfur (IV) oxide, chlorine, hydrogen sulfide and carbon oxide (II). In an anoxic environment, PAN films will show selective sensitivity to chlorine. The presence of water molecules in the investigated air should not affect the gas sensitivity of PAN films.
