摘要：

Blending Polytetrafluoroethylene (PTFE) to PA6 at different compositions was produced in a corotating twin-screw extruder, where PTFE acts as the polymer matrix and PA6 as the dispersed phase. The effects of PA6 content on the tribological properties of the composites were investigated. The worn surface morphologies of neat PTFE and its composites were examined by scanning electron microscopy (SEM), and the wear mechanisms were discussed. The presence of PA6 particles dispersed in the PTFE continuous phase exhibited superior tribological characteristics to unfilled PTFE. The optimum wear reduction was obtained when the content of PA6 is 30 vol%. POLYM. COMPOS., 31:3842, 2010. (C) 2009 Society of Plastics Engineers
