摘　　要：传统的油基润滑剂在使用过程中通常存在冷却性能差,易造成环境污染等问题,近年来绿色环保的水基润滑逐渐受到科学家们的关注.水由于自身黏度低且易挥发等特点,其作为润滑剂时润滑效果不佳,因此亟待发展高效的水基润滑添加剂来改善其摩擦磨损性能.在本文中,作者综述了近年来石墨烯基纳米材料的功能化改性及其作为水基润滑添加剂的最新研究进展,总结了其在摩擦过程中的润滑机理,并对目前石墨烯水基润滑添加剂存在的问题及今后重点研究内容进行了展望.The phenomenon of friction and wear is widespread in industrial production and daily life,resulting in a large amount of energy consumption and waste of resources.Therefore,it is particularly important to reduce friction and wear and improve the lubrication performance of mechanical equipment.The key to improve the lubrication performance of water-based lubricant and thus extend the service life of mechanical equipment is high-performance lubricants.Traditional oil-based lubricants have good lubricating effects and are not volatile.However,they usually show poor cooling performance during use and are likely to cause environmental pollution.In recent years,green and environmentally friendly water-based lubricant has gradually attracted the attention of scientists.Due to its low viscosity and volatile characteristics,neat water has poor lubrication effect as a lubricant.Therefore,it is urgent to develop efficient water-based lubricating additives.Graphene has excellent mechanical properties,thermal conductivity,anti-friction and anti-wear properties,which is a potential candidate as a high-performance additive for water-based lubricant.Therefore,this review summarizes the different functionalizations of graphene-based nanomaterials and their applications as water-based lubricating additives.This article mainly includes three parts:the various functionalization approaches of graphene-based nanomaterials and their applications in water lubrication;the corresponding mechanisms of friction-reduction and anti-wear of graphene-based nanomaterials;and the outlook of current problems of graphene-based nanoadditives in water lubrication.Firstly,four types of graphene-based nanohybrids with different functionalizations and their research progress as water-based lubricating additives were introduced.(1)Inorganic nanoparticles-functionalized graphene nanoadditives.Inorganic nanoparticles,e.g.metal nanoparticles,metal oxide or sulfide nanoparticles,and nanocarbons were usually used as nanoadditives to improve the friction and w
