Viscous microstructure preparation method

Abstract

A method for manufacturing viscosity microstructure comprises the procedures as follows: a) a base plate and a mould are prepared and the bottom of the mould is provided with a plurality of nano-scale sockets; b) a liquid impression layer is arranged on the base plate; c) the mould is pressed under the base plate, so the liquid impression layer goes into the socket to a preset depth, thus forming a substrate and a nano-bulge arranged on the substrate; and air in the socket is compressed; d) the impression layer is turned into solid state by solidification; and e) demoulding, the mould is pulled upwardly off the base plate. Due to the bounce produced by the compressed air in the socket, the nano-bulges formed in the socket can be withdrawn from the sockets easily. The substrate and the nano-bulges are combined together to form the viscosity microstructure. Therefore, the requirements of mass production and low cost can be met.

Description

technical field [0001] The invention relates to the manufacturing technology of nanostructures, in particular to a method for manufacturing viscous microstructures. Background technique [0002] Press, the existing known nano-stickers are mainly based on the technology known from the toe skin of geckos in nature, and mainly use the extremely high-density spatulate structure on the toe to generate van der Waals force on its adsorption surface to achieve adsorption. Effect. The existing nano-sticker achieves the adsorption effect by the high-density cilia on its surface. [0003] Among the currently known manufacturing techniques of nano-stickers, there are AndreK.Geim (A.K.Geim et al., Nat.Mater.2, 461 (2003)) of the University of Manchester in the United Kingdom, Metin sitti of the University of Carnegie Mellom in the United States (M.sitti et al ., J.Adhesion Sci.Technol., 18, p 1055(2003)), Ali Dhinojwala of Akron University (B Yurdumakan et al., Chem.Commun., p3799(2005...

AI Technical Summary

Problems solved by technology

But the disadvantage of this method is that not only expensive equipment such as electron beam lithography system, metal sputtering and plasma etching equipment are needed

In addition, its production rate is also very slow, and it cannot be produced in a large area, so it cannot meet the needs of mass production

At the same time, the fiber structure is manufactured by etching, so the characteristics of the fiber structure are also changed, making it impossible to reuse

[0005] As for Sitti, millions of artificially synthesized Silicone rubber fibers are prepared by the molding method. Experimental results show that this fiber can carry an object with a mass of 0.3 grams per square centimeter. Therefore, the disadvantage of this method is, Although the molding method can be quickly mass-produced, the mold cannot be reused, so it does not meet the needs of mass production

[0006] Dhinojwala and Zhao used synthetic carbon nanotubes as the spatulate structure on gecko toes. Although the adhesion force equivalent to the spatulate structure can be obtained, the disadvantage of this method is that the growth temperature of carbon nanotubes is too high, and Cannot grow directly on soft polymer substrates
