Method to prepare a nanosized-structure film of multi-phobic effects and its application

A composition for preparing films of multi-phobic effects comprising:

• a plurality of first type of surface-modified nanoparticles having a first type of fluorocarbon surfactant bound to a surface of a first type of nanoparticles;
• a plurality of second type of surface-modified nanoparticles having a second type of fluorocarbon surfactant bound to a surface of a second type of nanoparticles;
• a plurality of third type of surface-modified nanoparticles having a third type of fluorocarbon surfactant bound to a surface of a third type of nanoparticles, wherein the first, second and third surface-modified nanoparticles are less than about 100 nm in dimension;
• and
• a fluorocarbon filming substance.

A method of preparing a film of multi-phobic effects comprising:

• mixing fatty alcohol polyoxyethylene ether in water;
• providing a mixture of surface-modified nanoparticles including three or more types of surface-modified nanoparticles of less than about 100 nm in dimension, each type of surface-modified nanoparticles having a nanoparticle bound with a fluorocarbon surfactant;
• dispersing the mixture of surface-modified nanoparticles in the water, and
• adding perfluoro alkyl sulfuryl alkyl acrylate to form a colloid.
