Corrosion And Technology Of Superhydrophobic

In recent years, with the continuous development of science and technology, materials of superhydrophobic have broad application prospects in everyday life and the various production sectors, Thus superhydrophobic materials preparation and application of cause of great concern to all scholars. The hydrophobic material is by reducing the surface free energy and thus change the surface morphology of solid surfaces to control invasive ultra-hydrophobic. This thesis is based on this theory using a variety of technical means and other conditions by controlling the reaction time to build the micro and nano surface structures, Prepared by lower surface free energy of the structure to realize the control of surface wettability, Super-hydrophobic properties of the material to. the main research contents are as follows:1. Immersion method using etching solution prepared by the rough surface structure of the surface, uniform distribution in the same shape as the above nanoparticles, drops of water on the surface instability, contact angle can reach 120o. Then grafted hydrophobic reagents reduce the surface free energy, preparation of superhydrophobic materials completed. Be applied to a variety of corrosive environments are good hydrophobic properties. In a variety of chemical methods, solution immersion method is a simple preparation method, The method is characterized by simple, inexpensive, large area preparation.2. Primary cells is the most basic power generation device, the principle is widely used in the battery everyday theory. In the original battery in the current flow from the positive anode, cathode reduction reaction occurs, the negative electrode oxidation reaction. Both oxidation and reduction reactions can change the surface morphology of the material, the surface roughness of the metal to help increase the preparation of superhydrophobic materials. When the reaction was over, we will be prepared by copper and zinc into the low surface energy surface reagent in the graft, super hydrophobic preparation of copper and zinc Jibei. After a variety of corrosive environments on their corrosion resistance properties in a detailed study, It was concluded that preparation of superhydrophobic materials against corrosion. The approach we develop a simple process, production of cheap, saving, etc. In addition, this method allows the simultaneous preparation of two different superhydrophobic corrosion-resistant material, thus greatly improving the production efficiency.
