Abstract Polymer nanocomposites have gained significant attention in wear application due to possessing distinctive wear resistance absent in polymers. In this study, the graphene nanoplatelets (GNPs) and montmorillonite (MMT) nanoclay were used to fabricate the hybrid epoxy-based nanocomposites. The synergistic effect of nanomaterials on and wear behavior of nanocomposites was studied at three different temperatures by using pin-on-disk tests. The most significant wear resistance was obtained at 0.5 wt% MMT-0.15 wt% GNPs nanocomposites at the temperatures below the Tg (25 °C and 60 °C) and at 0.3 wt% GNPs at the temperature above the Tg (95 °C) in comparison to the neat epoxy. It was determined that MMT with high hardness and GNPs with self-lubricant properties and increasing the Tg, improve the wear properties.

石墨烯纳米片-蒙脱石杂化体系对环氧基纳米复合材料摩擦学行为的协同作用

摘要 聚合物纳米复合材料由于具有聚合物所不具备的独特耐磨性，在耐磨应用中受到了广泛的关注。在这项研究中，石墨烯纳米片 (GNP) 和蒙脱石 (MMT) 纳米粘土用于制造混合环氧基纳米复合材料。通过使用针盘试验研究了纳米材料在三种不同温度下对纳米复合材料的协同作用和磨损行为。在低于 Tg（25°C 和 60°C）的温度下，0.5 wt% MMT-0.15 wt% GNPs 纳米复合材料和在高于 Tg（95°C）的温度下，0.3 wt% GNPs 获得了最显着的耐磨性与纯环氧树脂相比。已确定具有高硬度的 MMT 和具有自润滑性能并提高 Tg 的 GNP 可改善磨损性能。
