Influence of Preliminary UV Irradiation on the Formation of Carbon Nanofibers on the Surface of Chlorinated Polyvinyl Chloride Under the Action of a High-Power Ion Beam

The influence of preliminary ultraviolet (UV) irradiation on the formation of carbon nanofibers on the surface of chlorinated polyvinyl chloride with the addition of ferrocene (10% of the polymer mass) is studied under the action of a high-power ion beam of nanosecond duration. Ultraviolet irradiation provides partial dehydrochlorination of the chloropolymer surface layer, causing a change in its thermodynamic properties, and due to this it affects the formation of carbon nanofibers during subsequent irradiation with a high-power ion beam. In contrast to thermal dehydrochlorination in air, ultraviolet irradiation makes it possible to reduce the temperature of the surface layer and thus reduce the negative effect of chloropolymer oxidation. The possible mechanisms of the influence of preliminary ultraviolet irradiation on the formation of carbon nanofibers on the surface of the chloropolymer under study are considered.
