UV-curable epoxy acrylate (EA) oligomeric resin / SiO2 nanocomposite coating was prepared by the sol-gel process. The effect of EA resin on the sol-gel process was studied. It was found that when EA content is higher than 85%, the so-gel system becomes turbid while EA content is lower than 85%, the system is transparent and homogeneous. It was demonstrated that a no-crack integrated cured film could be obtained via UV curing technique. It was proved that incorporation nano-particles of SiO2 into EA coating ...
