摘　　要：实现黏附可控是解决微/纳机械产品黏附失效问题和发展先进黏附材料及新型微操作/微装配技术等的有效途径.基于该研究背景,针对干燥不带电系统,对近年来发展的几类黏附调控方法进行了综述,从表面改形、材料改性及外场控制三方面介绍了织构、涂层/薄膜和复合材料、速度、温度、外力和磁场在黏附调控方面的研究进展,分析和总结了各类方法的黏附调控机理、关键影响因素和特点,并指出了应用领域,介绍了多手段复合调控黏附方法的最新研究成果.最后,探讨了当前黏附调控方面存在的问题和未来可能的发展方向.With the rapid development of micro/nano technology,human beings have stepped into a research field in which scale effect and surface effect play a leading role.In this field,the micro adhesive forces such as van der Waals force,electrostatic force and capillary force become significant compared with the macro forces such as gravity and inertial force.In dry and uncharged environment,the intermolecular van der Waals force is the main source of adhesion.On the one hand,adhesion is one of the main factors affecting the stability and surface damage of micro/nano-mechanical products and needs to be weakened and overcome.On the other hand,in order to develop multifunctional switchable adhesives and micro-manipulation/micro-assembly technologies,the enhancement and utilization of adhesion have attracted the interests of researchers.Under this context,the realization of self-regulation on surface adhesion according to performance requirements has become a research hotspot in recent years.This review attempted to present the research progress of adhesion regulation methods from the aspects of surface morphology modification,material modification and field control.Firstly,the role of surface morphology modification through texturing in reducing adhesion in the magnetic storage devices and microelectromechanical systems was introduced.It was found that the adhesion-reduction mechanisms of textures were the decrease of contact area and the increase of interface interval.The key influencing factors included the shape,area density and orientation of textures.The characteristics of different bionic textures and main parameters affecting the adhesion strength were described.It was demonstrated that the adhesionenhancement mechanisms of textures were the decrease of effective modulus and the increase of contact area.The adhesion switching effect depended on the structure,alignment state and area density of textures.Secondly,the adhesion regulation performances of material modification through surface coating/film were discussed.
