Two-dimensional (2D) lamellar materials have unique molecular structures and mechanical properties, among which molybdenum disulfide (MoS2) graphitic carbon nitride (g-C3N4) with different interaction forces served as reinforcing phase for polytetrafluoroethylene (PTFE) composites in the present study. Thermal stability, tribological thermomechanical properties of were comprehensively investigated. It was demonstrated that g-C3N4 improved elastic deformation resistance thermal degradation characteristics. The addition significantly enhanced anti-wear performance under loads speeds. results indicated PTFE reinforced by provided better because bonding strength derived from hydrogen bonds (H-bonds) stronger than MoS2 van der Waals force. Consequently, exhibited properties. result this work is expected to provide a new kind functional filler enhancing polymer composites.
