Composite nanoparticle additives of hybrid layered double-hydroxide/graphene nanosheets (LDH/GO) and layered double-hydroxide/molybdenum disulfide (LDH/MoS₂) have been fabricated by electrostatic self-assembly. The morphologies and compositions are confirmed by FESEM, EDS, XRD, Raman, and FT-IR. Zeta potential testing confirms that the composite nanoparticles have good dispersion stability in poly-α-olefins-4 (PAO-4). Meanwhile, the nanocomposites as additives can dramatically enhance the lubricating properties of PAO-4. Research results indicate that the good friction and antiwear properties of LDH/GO and LDH/MoS₂ composites can be attributed to the synergistic lubricating effects between LDH and GO or MoS₂.

基于水滑石作为高性能润滑油添加剂的复合纳米粒子

通过静电自组装制备了层状双氢氧化物/石墨烯纳米片（LDH / GO）和层状双氢氧化物/二硫化钼（LDH / MoS ₂）的复合纳米颗粒添加剂。形态和组成由FESEM，EDS，XRD，拉曼和FT-IR证实。Zeta电势测试证实了该复合纳米颗粒在聚α-烯烃-4（PAO-4）中具有良好的分散稳定性。同时，作为添加剂的纳米复合材料可以显着增强PAO-4的润滑性能。研究结果表明，LDH / GO和LDH / MoS ₂复合材料的良好摩擦和抗磨性能可归因于LDH与GO或MoS ₂之间的协同润滑作用。
