一種納米結構表面及其原位制備方法

Summary

The present invention relates to a nano-structured surface, including the base layer, the base layer and the large number of fixed nanoparticles. The surface of the water contact angle greater than 145 degrees. The invention also relates to a method for preparing nano-structured surface in situ, including the use of a silicon containing precursor, a water-soluble catalyst and low surface energy compound handle base layer, the base layer and treated in an ammonia gas atmosphere in the curing, constructed on the base layer nanostructured surfaces. Using this in-situ preparation of nano-structured surfaces prepared while having a surface roughness and low surface energy and therefore have excellent hydrophobic properties and larger water contact angle, the surface of the leaves form a bionic. The nano-structured surface can be easy and durable self-cleaning effect.
