2J85Material Superhydrophobic Surface Preparation Process Research

In recent years, people pay more and more attention to hydrophobic surface, whichhas a very broad application prospects in the industrial and agricultural production andpeople’s daily life. To build super-hydrophobic materials with nano-interface in basicscience and applications is extremely significance. The content of this thesis is based onultra-thinning effect of liquid nano-floating rotor micro gyroscope rotor surfaceultra-sparse nature of the study, the steady growth of hard magnetic materials with largesurface contact angle of the super-hydrophobic layer, using three methods to processthe2J85surface of super-hydrophobic. The main contents include:Using a combination of methods of chemical etching and surface fluorination,successes in preparing the substrate of super hydrophobic surface based on the2J85material, the contact angle can reach152°, and in the experiment studied the impact ofthe etching time and corrosion of the concentration on hydrophobic nature.Using the template method, the porous anodic alumina film as a template, thepolymerization of the PDMS pouring on the surface of the substrate, forming anano-scale columnar surface structure arrangement consistent with the aluminamembrane pore，surface contact angle can be increased to154°，studied the effects ofchemical composition and the surface of special structure of super hydrophobic in thePDMS membrane on hydrophobic nature.Using electrochemical deposition method, growth a layer of fourteen acid coppercluster crystals structure on the surface of the2J85material, formed irregularconcave-convex shape, the highest value of surface contact angle of154.5°, analyzedthe impact of deposition time on the super-hydrophobic nature.
