Triboelectricity in the pairs of polymeric materials

Abstract

The influence of electricity of polymeric films and knitted fabrics on friction parameters is analyzed in this work. The variations of the dynamic friction force were determined (under standard DIN 53375) in polymer sliding on the stands made of glass (organic and nonorganic). The dependencies of these variations on the polymer nature and stand mode were analyzed. The determined values of dynamic friction coefficient and dynamic friction force of 10 polymeric materials from the point of view of different stands are presented. The dependencies of friction parameters on triboelectricity and its influence on the formation of adhesion bonds between the components of the sliding pair are described.

Friction coefficient dependence on electrostatic tribocharging

“…For instance, macroscopic crystals were formed by self-assembly of polymer spheres charged by contact electrification31 and surface charging by scratching with a scanning AFM tip was also observed32. In a different context, the force applied to textile thread was shown to depend on the nature and electrostatic charging ability of the sliding thread supports33. Nakayama34 scratched sintered alumina, soda lime glass, Si 3 N 4 and PTFE with a diamond stylus, finding concurrent changes between potential and friction force.…”
