摘　　要：据此,本综述主要介绍了SiO_(2)纳米颗粒的润滑机理与影响因素,详细论述了SiO_(2)纳米颗粒在液体润滑、固体润滑领域的相关研究与应用现状,包括其在实际应用时所采用的相关表面处理与改性等手段。重点介绍了SiO_(2)纳米颗粒在提高聚合物基复合自润滑材料中的作用和巨大应用潜力。最后,对现有SiO_(2)纳米颗粒在自润滑领域中的应用与发展进行了陈述和展望。In recent years,the maintenance or replacement of materials caused by friction loss has brought huge economic losses.In order to reduce the loss of materials as much as possible,the design and development of materials with self-lubricating function has become a research hotspot.Because of its small size and high surface activity,nanoparticles have exhibited excellent tribological properties,and have received extensive attention in tribology field.Among them,SiO_(2) nanoparticles have excellent tribological properties due to their high hardness and sphericity.The application of SiO_(2) nanoparticles in the field of self-lubrication can be divided into liquid lubrication and solid lubrication.The liquid field refers to that when SiO_(2) nanoparticles are added to the liquid lubricant as an additive,the lubrication effect of the lubricant can be significantly enhanced.The solid field refers to the fact that the wear resistance of raw materials can be significantly enhanced when SiO_(2) nanoparticles are compounded with other particles to make solid self-lubricating composites and further applied to paint/coating designs.Currently,most researchers mainly elaborate on one of the above two types of application fields,which makes readers lack a comprehensive understanding and thinking about the practical application of SiO_(2) nanoparticles.Therefore,this review mainly introduces the lubrication mechanism and influencing factors of SiO_(2) nanoparticles,and discusses the relevant research and application status of SiO_(2) nanoparticles in the field of liquid lubrication and solid lubrication in detail,including the relevant surface treatment and modification means adopted in practical application.The role and great potential of SiO_(2) nanoparticles in improving polymer matrix self-lubricating materials in solid self-lubricating composites were introduced.Finally,the application and development of SiO_(2) nanoparticles in the field of self-lubrication are described and prospected.
