We report the synthesis results of cerium doped hybrid polymer and its performance as a corrosion protection material for carbon steel sample. A precursor of hybrid inorganic-organic polymer was synthesized from 3-(Trimethoxysilyl)propyl-methacrylate (TMSPMA) monomer by using sol-gel method. Cerium inhibitor was doped into the hybrid polymer precursor by mixing the precursor with a cerium nitrate dehydrate in the solution phase. The resulted material was then spincoated on the glass and silicon substrates and then photopolymerized using UV light. The structure and properties of the cerium doped hybrid polymer were characterized using the FTIR spectroscopy, thermal gravimetry analysis, and hardness test using Mohs scale. For corrosion study, the synthesized material prepared on the carbon steel substrate and measured in aqueous sodium chloride (3.5 M) using electrochemical potentiodynamic method. The results showed that the cerium doped hybrid polymer can reduced the corrosion rate of the carbon steel substrate, and we found that the corrosion rate is lower than the carbon steel coated with hybrid polymer without cerium.
