Method to prepare a nanosized-structure film of multi-phobic effects and its application
A method to prepare multi-phobic effects nanosized-structure film and its application are described, which features nanosized silica, titanium oxide and zinc oxide compounded materials of previous size 3-100 nm are in-situ combined with substrate through fluorocarbon surfactants and perfluoro alkyl filming substance under specific conditions to form a nanosized-structure film. The reaction between fluorocarbon surfactants and hydroxyl groups on surfaces of nanosized particles renders the modified nanosized particle and nanosized film having extremely high chemical stability, resistance, and the capacity to repel and disperse water, oil, bacteria, organic dust, gas, electricity, magnetism and light (i.e., multi-phobic effects). This technology may be widely used in surface modification of fabric, chemical fiber, cotton, wool, glass product, brick-stone concrete and wood wall.
