Preparation Of Wood-like Structured By The Method Of Morphology Genetic With Superhydrophobic Properties

Superhydrophobic materials have received tremendous attention in recent years because of its special properties such as water-proof,anti-pollution,etc.It becomes hotspot research in functional material fiel,and the preparation methods to acquire excellent superhydrophobic surface are key to the research.The preparation method of superhydrophobic materials has many.However,these methods are mainly prepared by chemical principles,the structure of the surface structure of artificial pre-designed geometric patterns.So scientists will focus on the perfect hydrophobic structure of nature,but based on the idea of bionics can only be roughly copied out of the surface structure of the leaves of animals and plants,the nature of the surface of organisms through the evolution of the special fine micro-nano structure is difficult to achieve.The products retained the natural structure of the bio-templates with superhydrophobic materilas.This fabrication method provides a new idea to obtain efficient superhydrophobic surface broadening the research scope of morph-genetic materials.Therefore,in this paper,the superhydrophobic surface was constructed on the surface of Si,metal and organic matter.The main contents and conclusions are listed in the following:(1)We used lauan,white pine and manchurian ash wood as a template,which were sintered in Ar to prepare the Biomorphic Porous Carbon with the high-fidelity surface structure of the wood cell wall.After modified by FAS,their surface exhibited excellent superhydrophobic properties.It is proved that the Biomorphic Porous Carbon structure of the woody cell wall has superhydrophobicity.(2)Biomorphic porous Carbon were served as templates to produce superhydrophobic surface by electroplating copper.The copper/ecoceramic(Cu/C)composites retained the macromorphology and microstructures of the original wood cell wall templates.And the influence of different parameter on the superhydrophobic performance were also discussed.(3)The structure of the biomorphic porous Carbon were fabricated by the metal-assisted chemical etching(MaCE)on the silicon substrate;We used Cu/C as a template,the biological Cu which on the Cu/C surface act as catalyst to accelerate the reaction rate,finally prepare the hydrophobic structure of silicon substrate.(4)In the wood porous carbon surface electroplating copper,in contact with the porous carbon can get wood reverse structure of the copper surface.After modified by FAS,their surface exhibited superhydrophobic properties.Analyzing the effect of changing the process parameters to contact angle,and the optimum conditions were summarized.(5)The hydrophobic structure of the biomorphic porous Carbon were prepared on the surface of epoxy resin using the templating method.We use the porous carbon carbon as a template,on the surface of the epoxy resin to get porous carbon porous structure of the reverse.Analyzing the effect of changing the process parameters to contact angle,and the maximum contact angle is 154°.
