The electrochemical assays showed that the coatings possess an excellent long-term stability at high corrosion resistance of up to 10 GΩ cm 2 and current densities about 6 orders of magnitude lower than that of the bare carbon steel. Wei Chen a, Yuansen Liu b, Changan Xu b, Yuan Liu a and Qi Wang a a The State Key Laboratory of Polymer Materials Engineering, Polymer Research Institute of Sichuan University, Chengdu 610065, China. Elemental composition of siloxane films obtained by XPS (measured at 632.8 nm) decreased from 1.43 to 1.28 analysis.

The peak at 930 cm 1 and a broad peak at about ness. XPS imaging analysis has been applied in understanding the delamination problems of siloxane coatings on polymethyl-methacrylate (PMMA) polymer. Synthesis and properties of an intrinsic flame retardant silicone rubber containing phosphaphenanthrene structure. The peak at 1 600 cm 1 is associated with the particulates associated with an increase in surface rough- CO group.

After identifying the optimum proportion of polymeric and silica phase for the formation of a highly ramified structure (MMA/TEOS = 4), increasing concentration of Ce( IV) ions (0.1% 87%) and enhances the polymerization of organic moieties. The recent development of X-ray Photoelectron Spectroscopy (XPS) instrumentation with spatial resolution down to several microns has advanced the capability of elemental and chemical state imaging. The films were prepared via the sol–gel route from radical polymerization of methyl methacrylate (MMA) with 3-methacryloxy propyltrimethoxysilane (MPTS) followed by acidic hydrolysis and condensation of tetraethoxysilane (TEOS). This study reports on the characterization of cerium doped organic–inorganic hybrid coatings by correlating their structural properties with the corrosion protection efficiency of coated carbon steel.
