HYHOBIC POLYMETYLHYDROSILOXANE BASED HYBRID FOR COATING APPLICATIONS

摘要

PURPOSE: A fluorine-modified polymethylhydrosiloxane and a hybrid are provided to improve mechanical properties of a coating membrane, especially abrasion resistance, and to improve anti-fouling performance by controlling a surface roughness of a coating film. CONSTITUTION: A fluorine-modified polymethylhydrosiloxane is obtained by grafting a polymer with a double bond comprising fluorine to a polymetylhydrosiloxane molecule by using a platinum catalyst, and partially modifying the polymethylhydrosiloxane by fluorine, and is in chemical formula 1. Functional groups of the polymer with a double bond comprise a vinyl group, an alkyl group, an acryl group, or a methacryl group. In modifying process 10-90% of Su-H functional groups included in the polymethylhydrosiloxane is modified.
