The phenylsilanetriol was prepared by hydrolysis of penyltrimethoxysilane (PTMS), and followed condensation reaction for increase of molecular weight. We synthesized urethane structure using phenylsilanetriol with 4,4-methylenebis(phenylisocyanate) and 1,4-diazabicyclo[2.2.2]octane. Then, the end groups of monomer were converted acrylate for using crotonyl chloride. A novel plastic hard coating materials were prepared by sol-gel process by using inorganic material (CS, colloidal silica AS-40) and organic material silane (MPTMS- methacryloxypropyl trimethoxysilane) with the prepared silicon monomer. Thereafter, radical initiator (irgacure: hydroxyl-cyclohexyl phenyl ketone) was added to the synthesized coating solution to perform UV curing. The coating materials were identified by 1H NMR, thermogravimetric analysis (TGA) and Photo-DSC investigations. |
