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 Due to the bounce produced by the compressed air in the socket, the nano-bulges formed in the socket can be withdrawn from the sockets easily.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
The present invention is relevant with the manufacturing technology of nanostructure, is meant a kind of manufacture method of viscous microstructure especially.
Background technology
Press, existing known nano-sticking paper mainly is the technology of being learnt by the toe skin of occurring in nature gecko, mainly utilizes the cochleariform process structure of very high-density on the toe to come its absorption surface is produced Fan Dewali, to reach the effect of absorption.Existing nano-sticking paper reaches adsorption effect by its surperficial high density cilium.
In the manufacturing technology of at present known nano-sticking paper, in respect of AndreK.Geim (the A.K.Geim et al. of Britain Manchester university, Nat.Mater.2,461 (2003)), Metin sitti (the M.sitti et al. of U.S. Carnegie Mellom university, J.Adhesion Sci.Technol., 18, p 1055 (2003)), the Ali Dhinojwala of Akron university (B Yurdumakan et al., Chem.Commun., p3799 (2005)) with the Yang Zhao (Y.Zhao of U.S. Atlas Scientific company, J.Vac.Sci.Techno.B, 23 (1), p331 (2006)) etc. four groups, the material that the above two use is macromolecule, and both then use CNT the back.
