Description
Technical field
The present invention relates to a kind of making method with bionic micro-nano structure surface material of marine anti-pollution function.
Background technology
In warm seawater, only need a few weeks longer just can grow 1 decimeter fouling organism, halobiontic adhering to boats and ships and maritime facilities brings great harm.The current material that utilizes the bionics techniques preparation to have anti-pollution function enjoys the investigator to pay close attention to, and is subjected to the attention of more and more researchers in the world.Compare with synthetic material, the surface tissue of natural biological presents the micro-nano hierarchy structure with some specific function of some natures, for example, the resistance when moving about not only can be effectively reduced on the placoid scale surface that shark has a rib-like, and can prevent the growth of fouling organism; The papillary structure of lotus leaf surface makes lotus leaf have good ultra-hydrophobicity and automatically cleaning ability or the like.These micro nano surface structures are that biological optimal development is come by long-term genetic evolution, and being nature obtains by eliminating screening many times in reaching the evolutionary process in 500,000,000 years, is the elite that nature is left the mankind for.Therefore, effectively utilize bionics techniques, copy the surfacing with marine anti-pollution function, can shorten the design cycle of antifouling micro-nano structure greatly, raising is designed to power, produces the material with wide spectrum anti-pollution function.
But, because marine organisms all are to live in the seawater, compare its surface and surface what contact all is seawater with terrestrial organism, and common bionics techniques can't be applicable to marine organisms fully, and therefore how using reasonably effective bionics techniques is a major issue.
Summary of the invention
Making method with bionic micro-nano structure surface material of marine anti-pollution function of the present invention, form by following steps:
A, employing wet method replica technique are made macromolecular material negative sense stay in place form, the organism surface that has antifouling ability in the ocean is cleaned, the aqueous solution of PVA is poured into its surface, after treating the moisture evaporation in the solution, the PVA film that forms is taken off from organism surface, formed the negative sense template with organism surface microstructure of macromolecular material; Wherein the concentration of the PVA aqueous solution is 5%～40%;
B, configuration PDMS performed polymer or TPU solution or PU solution are mixed evenly by PDMS monomer and linking agent, and its quality proportioning is the PDMS monomer: linking agent=10～20: 1, and leave standstill and discharged the air of sneaking in 10-20 minute; Or TPU is dissolved in butanone or dimethyl formamide or the tetrahydrofuran (THF), be mixed with 2-20% solution; Or PU is dissolved in dimethyl formamide or N,N-DIMETHYLACETAMIDE or the N-Methyl pyrrolidone, be mixed with 2-20% solution;
C, PDMS performed polymer or TPU solution or PU solution are watered on the negative sense template of making, treat to separate with the negative sense template after performed polymer completely solidified or the solvent evaporates, form bionic micro-nano structure surface material with marine anti-pollution function.
Making method with bionic micro-nano structure surface material of marine anti-pollution function of the present invention has following advantage: 1. need not drying treatment is done on halobiontic surface, and the wet method that directly adopts water miscible macromolecular material is duplicated the negative sense template, prevented because the source organism surface structural damage that processing such as drying cause makes the structure of bionical making and source organism surface structure in full accord;
2. anti-fouling material is a kind of water white elastopolymer, has very strong close organic performance and hydrophobic performance, has excellent elasticity, chemical stability, heat-resisting winter hardiness and erosion resistance simultaneously; As the base material of micro-processing technology of research marine anti-pollution, it has shown very desirable material feature: nontoxic pollution-free, excellent hydrophobic property, automatically cleaning, prevent that marine organisms from adhering to etc.;
3. method of the present invention is simple, good operation, and easy to control, cost is low; Mould material low price, proportioning process are simple;
4. the negative sense template can be used repeatedly, is fit to scale operation.
