Preparation method of biomimetic gecko composite microarray

Abstract

The invention provides a preparation method of a bionic gecko composite microarray, relating to a preparation method of setae on bionic gecko feet. The preparation method of the bionic gecko structured composite microarray comprises the following steps: (1) preparing a TiO2 nanotube microarray by adopting an anodic oxidation method; (2) impregnating the prepared TiO2 nanotube microarray in a trichloromethane solution of polydimethylsiloxane (PDMS) and taking out and curing the TiO2 nanotube microarray, thus obtaining a TiO2 / PDMS composite microarray. The preparation method of the setae on bionic gecko feet is simple to operate, is controllable in experiment parameters and low in cost and can be used for preparing the elastic silicone rubber coated TiO2 nanotube bionic gecko feet microarray. The area, setae diameters and height of the bionic gecko feet nano array are respectively 1-8cm<2>, 20nm-4mu m and 0.5-5mu m.

[0001] The invention relates to a preparation method of a bionic gecko composite microarray. Background technique

[0002] The excellent physiological functions of many animals have attracted the attention of scientists from all walks of life for centuries. For example, mosquitoes can easily adhere to human skin to bite; dung beetles living in a sticky and moist soil environment have excellent anti-adhesion functions; The smooth glass comes and goes freely. The common feature of the above-mentioned animals is that they all have a seta structure, and the difference in the architecture of the seta groups leads to the diversification of their functions. Among them, the kung fu on the gecko's feet is particularly amazing. Whether it is in the air environment, in the water or in a vacuum environment, the adhesion on its feet will not fail. Wall-climbing robot has a wide range of applications in civil, military and aerospace, so it has been paid more and more at...
