Abstract
Herein, a novel strategy of oil storage and transportation in polytetrafluoroethylene/porous polylactic acid/polydopamine/rapeseed pollen (diatomaceous earth)/paraffin wax ternary skeleton (PTFE/PPLA/PDA/POL(DE)PW) was developed to enhance the tribological performances of epoxy resin (EP). Importantly, a new biomass “pool-channel” structure was established using PPLA as the oil channel and DE or POL as the oil pool. The addition of biomass “pool-channel” structure to EP matrices can result bifunctional EP composites with self-lubricating and self-healing properties. In addition, experimental and theoretical calculations have shown the successful construction of intelligent "pool channels" with high oil content, high oil retention, release/reabsorption of lubricants. Compared with pure EP, the friction coefficient and specific wear rate of the novel epoxy composite were reduced by up to 85.46 % and 94.25 %, respectively.
在此，我们开发了一种在聚四氟乙烯/多孔聚乳酸/多聚多巴胺/油菜花粉（硅藻土）/石蜡三元骨架（PTFE/PPLA/PDA/POL(DE)PW）中储油和输油的新策略，以提高环氧树脂（EP）的摩擦学性能。重要的是，以 PPLA 作为油通道，以 DE 或 POL 作为油池，建立了一种新的生物质 "池-通道 "结构。将生物质 "池-通道 "结构添加到 EP 基质中，可产生具有自润滑和自修复性能的双功能 EP 复合材料。此外，实验和理论计算表明，高含油量、高保油性、释放/再吸收润滑剂的智能 "池道 "结构已成功构建。与纯 EP 相比，新型环氧树脂复合材料的摩擦系数和比磨损率分别降低了 85.46 % 和 94.25 %。
期刊介绍：
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
