Problems solved by technology

[0003] Self-cleaning performance is the prerequisite for geckos and other organisms to walk freely on walls and reusable new intelligent adhesive materials. However, there is currently a lack of systematic research on how to measure the self-cleaning performance of bioadhesive systems and bionic adhesive functional surfaces, especially the lack of corresponding test devices.

Abstract

The invention discloses a test device and method for measuring the self-cleaning performance of a bionic adhesion functional surface. The invention belongs to the technical field of biomimetic material mechanics and functional surface design and preparation. The device comprises a bottom base plate, a horizontal linear displacement table, a first angle adjusting mechanism, a second angle adjustingmechanism, an L-shaped connecting plate, a vertical linear displacement table, a middle connecting plate, a first tension and compression sensor, an L-shaped supporting plate, a second tension and compression sensor, a sample table, a bearing sheet, a glass slide, a glass slide supporting plate and a vertical supporting plate. According to the invention, the self-cleaning efficiency of a functional surface of a to-be-tested sample can be measured, and the influence of different self-cleaning cycle times, different preloading forces and different microscale motion modes on the self-cleaning performance of the to-be-tested sample is studied.

Description

technical field [0001] The invention belongs to the technical field of bionic material mechanics and functionalized surface design and preparation, and specifically relates to a test device and method for measuring the self-cleaning performance of a bionic adhesive functional surface. Background technique [0002] Organisms such as geckos in nature not only have super-adhesive ability, but also can crawl freely on dusty surfaces, indicating that their adhesion system has a special "self-cleaning" performance. Unlike the well-known self-cleaning properties of the surface of lotus leaves, the self-cleaning properties of the gecko's adhesion system do not require the participation of water. The ability of geckos to perfectly coordinate and unify the two seemingly contradictory mechanical phenomena of strong adhesion and self-cleaning is closely related to the microstructure of their feet. Therefore, the research and biomimicry of such adhesive functional surfaces with self-cle...
