环氧树脂固有的脆性和较差的耐磨性严重制约了其在许多领域的实际应用。本文采用微纳结构的ZrO2/ ti3c2颗粒来改善环氧树脂的摩擦学和热力学性能。采用水热法在手风琴状Ti3C2表面合成了纳米ZrO2/Ti3C2微纳米结构粒子，并通过溶液共混和固化反应制备了ZrO2/Ti3C2环氧复合材料。研究了ZrO2/Ti3C2颗粒的表面形貌和ZrO2/Ti3C2/环氧复合材料的断口形貌。试验结果表明，ZrO2/ ti3c2颗粒的掺入可有效提高环氧树脂的磨损率、储存模量和玻璃化转变温度，这可能是由于微纳结构的ZrO2/ ti3c2与环氧基体之间存在强烈的界面相互作用。此外，通过分析ZrO2/Ti3C2/环氧复合材料的磨损表面和磨损碎屑，进一步揭示了其磨损机理。这项工作为改善环氧树脂的摩擦学和热机械性能提供了一个有希望的策略。
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/Ti3C2particle was employed to improve the tribological and thermo‐mechanical properties of epoxy resin. The micro‐nano structured ZrO2/Ti3C2particles are synthesized by hydrothermal growth of nano‐ZrO2onto 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/Ti3C2particles 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/Ti3C2particles, maybe ascribing to the strong interfacial interaction between micro‐nano structured ZrO2/Ti3C2and 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.
