This paper aims to explore polyaniline (PANI) as a lubricant additive to improve the anti-corrosion and tribological properties of ionic liquids (ILs) for actual applications.,ILs were synthesized by dissolving lithium salts in synthetic oil and were used as a base oil to prepare ILs-based greases. PANI was used as an additive. The tribological properties were investigated in detail and the anti-corrosion ability was also assessed via salt spray test. After friction test, the worn surfaces were characterized by scanning electron microscopy, Raman spectroscopy and X-ray photoelectron spectroscopy to analyze the lubrication mechanisms.,PANI not only reduces the corrosion but also improves the friction reduction and anti-wear abilities of the ILs-based greases. The analysis indicates that the protective films generated on the worn surfaces were responsible for the preferable anti-corrosion and tribological properties.,This paper provides an effective approach to improve the anti-corrosion and tribological properties of ILs for actual applications.,The peer review history for this article is available at: https://publons.com/publon/10.1108/ILT-11-2019-0469/

聚苯胺作为添加剂改善离子液体基润滑脂的摩擦性能和抗腐蚀性能

本文旨在探索聚苯胺（PANI）作为润滑剂添加剂，以提高离子液体（ILs）的抗腐蚀和摩擦学性能以供实际应用。通过将锂盐溶解在合成油中合成离子液体，并用作基础油制备基于 IL 的润滑脂。PANI 用作添加剂。详细研究了摩擦学特性，并通过盐雾试验评估了防腐能力。摩擦试验后，通过扫描电子显微镜、拉曼光谱和X射线光电子能谱对磨损表面进行表征以分析润滑机制。PANI不仅减少了腐蚀，还提高了ILs的减摩和抗磨能力-基润滑脂。
