Abstract :
The influence of rubbing conditions, and of concentration and dispersity of fillers on the parameters of the triboelectret state in polymeric coatings containing particular electroconducting (graphite, nickel) or dielectric (Teflon) fillers has been studied. The residual charge, the activation energy, and the temperature of the injected and polarized components of the triboelectret charge were found to increase with the sliding velocity, when small quantities (1 to 3%) of particulate metals were added; the effect of the residual charge in the coating and its relaxation time increased with filler dispersity. Similar effects were detected when higher quantities (4 to 15 vol.%) of dielectric fillers were added to the polymer
