The plastic sheet usually has a lower surface hardness than glass resulting in poor scratch resistance, easily damaged surface, and deteriorated transparency. In this study, UV-curable organic / inorganic hybrids were synthesized by sol - gel method to improve surface physical properties of hard coating. Both sol-gel reaction and fast UV-curing reaction were properly combined to improve the dispersion of the inorganic component in the urethane acrylate organic matrix. In addition, the effect of structural change of the coating material by various silica precursors on the surface characteristics of the coating layer was investigated using ATR FT-IR, surface hardness characteristics, optical transmittance and thermal decomposition behavior. |
