Development of Polymer Composites Based on Polytetrafluoroethylene and Detonation Nanodiamonds

Abstract

Studies of the development of methodological bases for synthesizing polytetrafluoroethylene modified with detonation nanodiamonds using ultrasonic irradiation of a composite mixture during pressing determined the optimal modes of ultrasonic irradiation. Polytetrafluoroethylene modified with detonation nanodiamonds (0.5 wt.%) had the best combination of strength and tribological properties. The wear resistance of the developed material increased by 15.8% whereas the coefficient of friction decreased by 13.6%.
