Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] Such as figure 1 , the present invention has a large-area production method of an anti-adsorption surface with a realistic shark skin appearance, and the specific steps of the method are as follows:

[0044] Step 1: Prepare rolling negative template device

[0045] (A) cut off the shark skin 200 * 100mm, rinse with clear water and deionized water 3-5 times respectively, and finish the cleaning of the shark skin;

[0046] (B) Soak the cleaned shark skin completely in 2.5% glutaraldehyde solution, place it in a constant temperature environment at 4°C for 7 hours, and complete the fixation of the shark skin;

[0047] (C) Rinse the fixed shark skin with 4% phosphate buffer solution for 10 minutes, then rinse it with water and deionized water for 5 times, then soak it in 50% ethanol for 15 minutes, 75% ethanol for 15 minutes, and 95% etha...

Abstract

The invention relates to a method for manufacturing larger-area anti-adsorption surface with an emulational shark skin appearance, comprising two steps: (1) manufacturing a rolling female template device; and (2) manufacturing the anti-adsorption surface by adopting the ultraviolet-light curing technology. The ultraviolet-light curing technology is used for curing material rapidly to form the surface in a needed structure by using the sensitivity of the material to ultraviolet light. The micro embossing moulding method is used for rapidly carrying out micro-replication and nano-replication to structural patterns under the micro-nano scale with low cost. The method uses the ultraviolet-light curing technology and the micro embossing moulding technology to manufacture the larger-area anti-adsorption surface with the emulational shark skin appearance. The method has good practical value and wide application prospect in the technical field of biomimetic manufacturing.

Description

technical field [0001] The invention relates to a large-area manufacturing method of an anti-adsorption surface with a realistic shark skin appearance, more particularly, refers to a method for manufacturing a realistic shark scale groove by combining ultraviolet light rapid curing technology and micro-imprinting plastic casting technology. Anti-adsorption surface with groove structure. It belongs to the technical field of biomimetic manufacturing. Background technique [0002] Marine biosorption brings great harm to the surface of ships and marine facilities in the ocean. On the one hand, biosorption will accelerate the corrosion of metals and shorten the service life; on the other hand, it will increase the surface resistance, resulting in a decrease in navigation speed and a waste of energy. Therefore, anti-adsorption technology is of great significance for energy saving and emission reduction. [0003] The traditional anti-adsorption technology is to coat the surface ...
