摘　　要：多孔储液材料因其优异的自润滑性能备受关注,特别是其孔隙结构参数与性能间对应关系的研究一直是学术界和工业界亟待解决的问题。针对该类多孔储液材料,从来源、制备方法以及摩擦学特性等方面对其发展脉络及面临的问题进行梳理和分析,认为在仿生关节软骨制备适合工业应用的摩擦副方面,如何提取关键仿生特征参数是关键。目前在进行服役可靠性、工况适应性分析时,多用孔隙率来表征多孔结构特征,在明晰孔隙形态参数(孔径,分布,贯通型等)与力学-物理性能、润滑状态之间的映射关系方面存在明显的不足,导致从优化孔隙形态参数入手实现多孔储液材料力学-物理性能与摩擦学性能的统一方面仍具挑战性。3D打印技术的快速发展有望解决当前多孔材料成形过程中孔隙形态参数不可精确控制的问题,并为其自润滑理论的发展提供有效试验手段。Porous liquid storage materials have attracted much attention because of their excellent self-lubricating properties.But the relationship between pore morphology parameters and product properties still remains an urgent problem to be solved in academia and industry.In order to solve this problem,the research development and problems faced by this kind of porous liquid storage materials are combed and analyzed from the aspects of bionic source,preparation methods and tribological characteristics.It is considered that how to extract the key bionic characteristic parameters is the key in the preparation of bionic articular cartilage friction pairs suitable for industrial application.Another thing is that porosity is often used to characterize the porous morphology structure in the analysis of service reliability and working condition adaptability at present.This results that the mapping relationship among pore structure parameters,such as pore size,distribution,penetration and so on,mechanical-physical properties and lubrication regime is still not very clear.Therefore,it remains challenge to realize the unity of mechanical physical properties and tribological properties by means of optimizing the pore morphology parameters of porous liquid storage materials.The rapid development of 3D print technology is expected to solve the problem that the pore shape parameters can not be accurately controlled in the current porous material forming process,and to provide an effective experimental means for the development of its self-lubricating theory.
