Preparation and Characterization of UV-curable Silicone Resin Containing Perfluorocyclobutyl Aryl Ether Groups

Silicone resin is a coating material with good performance. The improvement of its thermal stability and hydrophobicity has always been the pursuit of researchers. In this paper, a series of novel UV-curable silicone resins containing perfluorocyclobutyl (PFCB) groups were prepared by co-hydrolytic polycondensation. The structures of the resin precursor MDT-SH were characterized by FT-IR and 1 H NMR. The heat resistance of them was studied by TGA and DSC, and results show that the PFCB groups can significantly improve the high temperature resistance of the resins. Contact angle tests showed that hydrophobicity of them was also enhanced by the PFCB groups.
