The processes of electrization of polymer and composite polymer materials and coatings based on them have been studied during frictional interaction with raw cotton, depending on the type and nature of polymers and organomineral fillers. It has been established that the specificity of the contacting bodies (composite-cotton-raw) is determined by the processes of electrification of the composite polymer coatings affecting the surface layers and thereby affecting their electrophysical and physical-mechanical properties. It was found that a decrease in the electrification of composite polymer coatings improves their antifriction properties. This makes it possible to purposefully change and regulate the anti-electrostatic and antifriction properties of composite polymer coatings working in interaction with raw cotton. Thus, the occurrence of an electrostatic charge in the contact zone of the composite-raw cotton negatively affects the coefficient of friction, wear resistance and durability of composite polymer coatings, and also increases the fire hazard in the process of processing raw cotton. The main regularities of electrification and changes in the electrophysical properties of composite polymer coatings during sliding with raw cotton have been established. It is shown that the most effective effect on the electrostatic properties of composite polymer coatings is electrically conductive fillers (soot, graphite), which provide optimal physical and mechanical properties of anti-electrostatic composite polymer coatings. The aim of the study is to establish the regularities of the process of electrification of composite polymer materials and coatings based on them during frictional interaction with raw cotton and changes in their electrophysical, physical and mechanical properties.
