ABSTRACT

Based on the latest study of the super- hydrophobic surface results , this paper describe  the super-hydrophobic material characteristics, types, applications and the common  preparation of super-hydrophobic materials and research progress. With CuCl2 • 2 H2O and NaOH as raw materials, the method of solid phase is prepared for nano-particles of coppe ,and the super-hydrophobic film of nano-particles of coppe use the method of steep sub on the Pre-disposed glass. The results of experiment show that in the preparation of the whole process, whet get the raw materials act at low temperature. The moer NaOH can made the grains smaller. By adding a certain amount of polyethylene glycol can effectively reduce the copper oxide nano-reunion and the washing with water is opposite. Dispersed in ethanol,and dried at a certain temperature and 400 ℃ high temperature calcined three hours,we can get the hydrophilic film.The ethanol with 1% of stearic acid can turn it into the super-hydrophobic materials.Acid and alkalescent solution can effect the super- hydrophobic character. The acid erode it. Using electron microscopy study the super-hydrophobic surface and characteristic, the largest contact angle can reach 164°, the roll angle can reach 5°.;

Key words： Super-hydrophobic, nano-copper oxide film, solid state law, contact angle, roll angle
