自然界材料将结构与功能协同互补，表现出多种特异表面功能。已有工作多集中研究材料特性、表面微结构特征对单一特异表面效应形成机制的影响。探讨力、热、电等外场作用下材料表面效应、影响机制及不同表面效应相互间联系，可为实际仿生制备和应用提供必要的理论指导。本项目将以具有特异表面效应的典型生物材料及仿生材料为研究载体，采用多尺度力学的研究方法，通过实验、理论及数值模拟，系统研究力、热、电等外场条件下的表面黏附效应、浸润效应、输运效应及其宏微观影响机制，揭示多场耦合条件下材料性能、表面特征对三种表面效应的影响以及三种表面效应彼此间的相互关联，建立多场耦合、材料性能、表面特征、表面效应间的定性规律和定量关系，探索仿生材料智能表面的设计方法。项目涉及材料、力学、物理、化学、生物等多学科交叉，研究成果不仅有助于指导仿生材料的制备和实际应用，对智能材料表面设计提供新思想，更重要的是能够推进表面力学方向的发展。

Integration of structures and functions in nature's materials leads to differently surface functions. Most of the literatures focused on study of effects of material properties and surface micro-structure features on the mechanical mechanism of single surface effect. To investigate effects of force, heat as well as electricity on surface effects can provide theoretical guidance for biomimetic fabrications and real applications of future biomimetic materials. Based on typical biomaterials and biomimetic materials, effects of surface adhesion, wettability and transportation as well as the macro- and micro-mechanisms of surface effects under the action of multiple fields of force, heat and electricity will be investigated systematically in this project, using the method of multiple-scale mechanics with experiments, theoretical models and numerical simulations, in order to disclose influences of material properties and surface features on surface effects as well as the correlation among the three surface effects themselves. Qualitative rules and quantitative relations among the coupled fields, material properties, surface features and surface effects are aimed to be established, which should be helpful for the design of intelligent surfaces of biomimetic materials. Such a project is a multidiscipline one related to materials, mechanics, physics, chemistry and biology. The results should be helpful not only for biomimetic fabrications and real applications of future biomimetic materials as well as the design of future intelligent material surfaces, but also, the most importantly, for the development of surface mechanics.
