Problems solved by technology

[0004] The literature (JournalofMaterialChemicalA, 2013, 1: 13869-13877) reported a superhydrophobic surface preparation method using a millennium taro as a template and a special polymer as a coating. The preparation method of polymer is more complicated
The literature (Langmuir, 2006, 11:4917-4919) reported a method of using femtosecond laser to prepare superhydrophobic surface. The disadvantage of this method is that the femtosecond laser equipment is expensive

Abstract

The invention relates to a preparation method for a nano copper oxide super-hydrophobic coating. The preparation method comprises the steps that copper oxide nano particle raw materials are modified, and then prepared into the super-hydrophobic coating. The super-hydrophobic coating prepared through the preparation method has good pollution flashover preventing performance and icing preventing performance, the preparation method is simple and convenient, and low in cost.

Description

technical field [0001] The invention belongs to the field of materials science, and relates to a preparation method of a nano-copper oxide superhydrophobic coating. Background technique [0002] State Grid plans to build UHV power grids in North China, East China, and Central China ("Sanhua") in 2015, forming a "three vertical and three horizontal" ring network, and fundamentally solve the constraints of my country's large power transmission loss and unreasonable distribution of energy supply and demand. The key bottleneck of national economic development, and DC UHV transmission is one of the key technologies to meet this requirement. At present, there is still a big gap between my country and developed countries in the development and manufacture of DC UHV insulation materials. Key insulation materials are basically imported and controlled by others. Insulators act as insulation electrically and as support mechanically. my country's domestic air pollution is serious and t...
