Effect of SiO2 nanoparticles on the hydrophobic properties of waterborne fluorine-containing epoxy coatings

Effect of SiO2 nanoparticles on the hydrophobic properties of waterborne fluorine-containing epoxy coatings

A nano-composite coating was developed by adding nano-SiO2 to a home-made Waterborne fluorine-containing epoxy resin. The surface hydrophlicity of the coating was investigated by the contact angle with water. As the particle sizes of SiO2 changed from 7-18nm, the water contact angle of the films cha...
