Recent Progress of Biomimetic Dry/Wet Friction Adhesion Devices

In nature,organisms have evolved many unique dry/wet friction and adhesion organs to adapt to their living environment. Based on the deep study,understanding and summary of these natural friction/adhesion phenomena,researchers have put forward corresponding bionic surface and interface friction/adhesion mechanisms,theories and models to guide the synthesis of artificial intelligent friction/adhesion materials and smart application devices. At present,the design strategies of biomimetic friction/adhesion material systems and devices are mainly based on surface microstructure,surface/interface physical and chemical interactions,and mechanical deformation. However,with a deeper understanding of biological friction/adhesion mechanism,the design concept of coupling multi-strategies has gradually become the main research direction. In this design concept background,this paper reviews the latest research progress of biomimetic friction/adhesion devices from four parts:single strategy such as surface microstructure design,interface chemical modification,mechanical deformation control,and multiple coupling strategies. This paper also analyzes these design concepts of single and multi-strategies respectively,discussing the advantages and disadvantages of these design strategies. The innovation of different design principles,surface and interface friction/adhesion properties of these devices and their potential applications,and existing problems of them are also described. Finally,this review prospects the future development direction of biomimetic friction/adhesion materials and devices,and this review is of guiding significance to the research of surface engineering,biomedicine and microelectronics.
