Abstract

The unique mechanical properties and wear resistance of HDPE give it the potential as an alternative to frictional material. The current research focuses on using hybrid nanoparticles with various loading fillers to determine the best additive contents. The mechanical and tribological characteristics were examined and evaluated. The HDPE nanocomposite samples containing 0.5, 1.0, 1.5, and 2.0 wt.% filling content of AlO nanoparticles (NPs) and 0.5, and 1.0 wt.% of graphene nanoplatelets (GNPs) were fabricated. The results showed a good enhancement in the mechanical and tribological properties of HDPE composites with the presence of nano additives. The HDPE nanocomposites recorded the best performance with a loading amount of 2.0 wt.% with an equal ratio of hybrid nanofiller AlO NPs and GNPs.

摘要

高密度聚乙烯（HDPE）独特的机械性能和耐磨性使其具有作为摩擦材料替代品的潜力。当前的研究集中在使用具有各种负载填料的混合纳米颗粒来确定最佳添加剂含量。对其机械和摩擦学特性进行了检查和评估。制备了含有0.5、1.0、1.5和2.0重量百分比的氧化铝纳米颗粒（NPs）填充量以及0.5和1.0重量百分比的石墨烯纳米片（GNPs）的HDPE纳米复合材料样品。结果表明，纳米添加剂的存在使HDPE复合材料的机械和摩擦学性能有了良好的增强。HDPE纳米复合材料在负载量为2.0重量百分比且混合纳米填料AlO NPs和GNPs比例相等时表现出最佳性能。
