Study on hydrophobic properties of coatings enhanced by organofluorosilicone polymers

Abstract Hydrophobic materials are widely used in industry and life. It is of great practical significance to develop new hydrophobic materials. In this paper, organofluorosilicone polymers were prepared by low-cost and easily accessible process using organofluorosilicone prepolymers as reactants and under the action of organosilicon crosslinking agent. Infrared spectrum test showed that the prepared organofluorosilicone polymer had obvious C-F stretching vibration peak at 1211cm-1, which proved the effective synthesis of organofluorosilicone polymer. The test of contact Angle under water condition shows that the water contact Angle of coating materials added with organofluorosilicone polymer is larger. Therefore, organofluorosilicone polymer can be used as a kind of efficient hydrophobic additive to enhance the hydrophobicity of coating materials.
