Abstract:

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
