Abstract:

The friction and frictional electrification properties of Teflon TFE polytetrafluoroethylene, Teflon PFA tetrafluoroethylene-perfluoro-alkyl vinyl ether copolymer and Teflon FEP tetrafluoroethylene-hexafluoropropylene copolymer have been studied by rubbing them against polystyrene. Potentials generated on the fluorocarbon polymers were measured by the classical Faraday ice-pail method. The relationship of surface energy and chemical constitution of the fluorocarbon surfaces to kinetic coefficient of friction and frictional electrification properties was investigated by using the contact-angle technique. The effects of annealing were also investigated Results are discussed, and mechanistic explanations are proposed.
