A METHOD FOR PREPARING MULTI-SUBSTANCE DISPERSION-EFFECT THIN MEMBRANE WITH NANO-STRUCTURE AND THE USE THEREOF

摘要

A method for preparing multi-substance dispersion-effect thin membrane with nano-structure and the use thereof, characterized in that a composition material comprising nano silica, titania and zinc oxide with 3-100 nm primary particle size is combined with fluoro-carbon surfactants and a fluoro-carbon membrane-forming material under special conditions to form in-site nano-structure thin membrane on a base. Due to the reaction and action between the fluoro-carbon bonds and the hydroxyl groups on the surface of the nano particle, the modified nano particle and the obtained nano thin membrane have extremely high chemical stability and weatherability, and exhibit dispersion-effect on many materials, such as water, oil, bacteria, organic dust, gases, electron, magnetism, light, etc, i.e. a multi-substance dispersion-effect. This technique can be applied widely in surface modification, such as weave, chemical fiber, cotton, glass articles, tile concrete and woody structure wall.
