To improve performances of polymer based composites, the present study produces polytetrafluoroethylene (PTFE) -based composites containing graphene nanoplatelets (GnPs) without any solvents. Solid-state milling is performed using an attrition milling at room temperature, producing PTFE/GnP composite powders which GnPs are attached and embedded. The PTFE/GnP powder is hot-pressed at 400 °C to fully consolidate the powders. Yield stress of the hot-pressed composite shows an increase of 60 %, compared to the neat PTFE. Furthermore, Young’s modulus of the composite increases 223 %. The PTFE/GnP composites are investigated with varying volume fraction of GnPs in terms of mechanical properties and microstructures.
