Abstract
Abstract Polytetrafluoroethylene @ phenolic resin (PTFE@PR) core-shell particles were successfully synthesized through a versatile one-pot method, which were investigated in tribological characteristics. The core-shell structure was characterized by transmission electron microscopy (TEM), fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS). The results demonstrated that core-shell composites possess the lower friction coefficient and better anti-wear performance. Friction coefficient of the composite is about 0.178 as low as pure PTFE at 50 N and 0.033 m/s. Meanwhile, the wear volume of the composite was measured at 0.59 mm3 by rubbing 1 h, which is merely a fifteenth of pure PTFE (8.94 mm3). The chemical action of core-shell composites resulted in the uniform and integrate transfer film, so that outstanding tribological performances of core-shell composites were exhibited.
