UV curable organic/inorganic hybrid for hard coating based on organo-alkoxysilane and urethane acrylate |
| 초록 |
Hard-coating materials for improving the scratch resistance of transparent plastic substrate surface were prepared by combining a non-hydrolytic sol-gel reaction of organo-alkoxysilane using acidic catalyst and photopolymerization of unsaturated C=C groups. A radical photoinitiator was added to the organic-inorganic hybrid and the coated layer was crosslinked with UV-radiation. Various hybrid hard coatings were prepared depending on the contents of inorganic material. UV-cured hybrid hard coatings showed the improved surface hardness and excellent transparency. The sol-gel reaction was studied by attenuated total reflectance Fourier transform infrared spectroscopy. Surface hardness of UV-cured hybrid hard coating was evaluated by pencil hardness. Transmittance of hard coating was investigated by UV/Vis spectroscopy. |
