Abstract

Novel silicone-based coating materials were prepared by the copolymerization of alkoxysilanes with pre-synthesized tailored polyurethane/polyurea copolymer end-capped with siloxane. The structure of the pre-synthesized copolymer and that of the obtained silicone-polyurethane/polyurea copolymer (SPPU) with different hard segment (HS) contents were analyzed by an FT-IR spectroscopic method. The molecular weight and molecular weight distribution of the SPUU was determined by Gel Permeation Chromatography (GPC). The thermal properties of the SPUU copolymers were performed by Thermogravimetric Analysis (TGA). The mechanical and adhesion properties of the copolymers were also investigated by standard methods. Their morphology was studied by Scanning Electron Microscopy (SEM). The electrochemical impedance spectroscopy (EIS) evaluation shows that the protective and anticorrosion properties of these coating materials do not strictly depend on the hard HS content.
