Improved Tribological and Thermo‐mechanical Properties of Epoxy Resin with Micro‐nano Structured ZrO2/Ti3C2 Particles

Inherent brittleness and poor wear resistance of epoxy resin severely restricts its practical application in many applications. In this present, a micro-nano structured ZrO2/Ti3C2 particle was employed to improve the tribological and thermo-mechanical properties of epoxy resin. The micro-nano structured ZrO2/Ti3C2 particles are synthesized by hydrothermal growth of nano-ZrO2 onto the surface of accordion-like Ti3C2, and the ZrO2/Ti3C2/epoxy composites are fabricated by solution blending and curing reaction. The surface morphology of ZrO2/Ti3C2 particles and the fracture surface of ZrO2/Ti3C2/epoxy composites were investigated. Test results indicated that the wear rate, storage modulus and glass transition temperature of epoxy resin is effectively improved by incorporation of ZrO2/Ti3C2 particles, maybe ascribing to the strong interfacial interaction between micro-nano structured ZrO2/Ti3C2 and epoxy matrix. In addition, the wear mechanism of ZrO2/Ti3C2/epoxy composites were further revealed by analyzing their worn surfaces and wear debris. This work provides a promising strategy for improving the tribological and thermo-mechanical properties of epoxy.
