Abstract
The invention discloses a method for duplicating a micro-nanostructure. The method comprises the following steps: (1) selecting a raw material with a super-hydrophobic structure; (2) fixing the raw material to a mold; (3) mixing a polydimethylsiloxane (PDMS) prepolymer and a curing agent in a ratio of 10:1, performing uniform stirring through a glass plate, performing standing for 10 to 20 minutes, and removing bubbles through a needle; (4) pouring a PDMS mixture, which is obtained in the step (3), to the mold, performing standing for 10 to 20 minutes, and removing bubbles in PDMS; (5) performing drying and solidification in a room temperature environment, wherein the solidification time is 24 to 36 hours; (6) performing curing in a heat treatment manner; and (7) separating the cured PDMS from the raw material on the mold to obtain the needed structure. The method for duplicating the micro-nanostructure, provided by the invention, is simple in process, economic and suitable for batch production, and can be expanded to be applied to production and living.
Description
Technical field
The present invention relates to micro-manufacture field, be specifically related to a kind of method of copying micro-nano structure.
Background technology
At present, along with the development of nanometer embossing with and high resolving power, the cost feature low, transfer in enormous quantities that possessed be used widely.The micro nano structure of some natural materials of nature has special effect, how nanometer embossing is applied to occurring in nature and forms large-scale production to bring huge economic benefit still there is no good method.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the method for copying micro-nano structure provided by the invention, simple, cost is low, be suitable for applying.
Technical scheme: for solving the problems of the technologies described above, the technical scheme of employing of the present invention is: a kind of method of copying micro-nano structure, comprises the steps:
(1) choose the raw material with super-drainage structure;
(2) raw material is fixed on mould;
(3) PDMS prepolymer is mixed in 10:1 ratio with hardening agent, with glass plate, stir, standing 10～20 minutes, with syringe needle, remove bubble;
(4) PDMS mixture step (3) being obtained is poured on mould, standing 10～20 minutes, removes the bubble in PDMS;
(5) environment of putting into room temperature is dried and solidifies setting time 24～36 hours;
(6) adopt heat-treating methods to be cured;
(7) PDMS after solidifying is separated with the raw material on mould, obtain required micro-nano structure.
As preferably, the raw material adopting in described step (1) is cicada's wings.
As preferably, described step (6) is to solidify 2～3 hours at 60～70 ℃.
Beneficial effect: the method technique of copying micro-nano structure provided by the invention is simple, economic, is applicable to batch production; The method that copies micro nano structure can be expanded, preparation has the material of super-drainage structure, can play antifouling effect to the windowpane of buildings and glass outer wall, suppress microorganism to the adhesion of body surface etc., make it producing, bring into play huge effect among life.
Embodiment
Embodiment 1:
A method for copying micro-nano structure, comprises the steps:
(1) select the good cicada's wings of hydrophobicity;
(2) cicada's wings is cut to 2cm * 2cm structure, and is fixed on mould;
(3) get 10ml PDMS prepolymer, get 1ml PDMS hardening agent; After prepolymer is mixed by 10:1 with hardening agent, with glass bar, stir fully, stir 10 minutes; Standing 10 minutes of mixed uniformly PDMS mixture, then with syringe needle, bubble is chosen out, remove the bubble in PDMS.
(4) PDMS mixture step (3) being obtained is poured on mould, more standing 10 minutes, remove the bubble in PDMS.
(5) put into the environment of 20 ℃ and be dried and solidify, solidify 24 hours.
(6) adopt heat-treating methods to be cured: at 70 ℃, to solidify 2 hours.
(7) PDMS and cicada's wings are peeled off.Stripping process is very careful, because PDMS resilient material is easy to fragmentation, and directly encounters figuratum PDMS surface, can exert an influence to the micro-nano structure copying.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (3)
