Problems solved by technology

There are many methods for preparing superhydrophobic surfaces, but there are problems such as high requirements for equipment, poor applicability, and high selectivity for carriers. For example, methods such as plasma etching and laser etching have high requirements for equipment; Deposition methods, etc. can only be applied to conductive substrates, and the applicability is poor; template methods, etc. have high selectivity for carriers

Description

technical field [0001] The invention belongs to the technical field of surface treatment, in particular to a Co 3 o 4 Nano-array superhydrophobic material coating and preparation method thereof. Background technique [0002] Superhydrophobic material is a new type of material with special surface properties, which has important characteristics such as waterproof, anti-fog, anti-snow, anti-pollution, anti-oxidation, anti-corrosion, self-cleaning and prevention of current conduction. There are many methods for preparing superhydrophobic surfaces, but there are problems such as high requirements for equipment, poor applicability, and high selectivity for carriers. For example, methods such as plasma etching and laser etching have high requirements for equipment; The deposition method, etc. can only be applied to the conductive substrate, and the applicability is poor; the template method, etc. has high selectivity to the carrier. Therefore, how to adopt a simple method to pr...
