In this research, we used a sol-gel process to prepare UV-curable antiglare coatings. First the inorganic monomer tetraethoxylsilane was formed into colloidal silica by hydrolysis and condensation reactions. Then, added the couple agent 3- propyl methacrylate and surfactant fluoroalkylsilane (13F) to modify the colloidal silica. Finally, organic monomer dipentaerythritol hexaacrylate were added to form hybrid material.
