Abstract: A new photosensitive prepolymer phenyl glycidyl ether acrylate (PGEA) was synthesized from phenyl glycidyl ether (PGE) and acrylic acid (AA) as raw materials, triphenylphosphine as the catalyst and 4-methoxy phenol as the inhibitor. Then, nano-SiO2 was treated with cetyltrimethylammonium bromide and surface-modified with silane coupling agent γ-meth-acryloxypropyltrimethoxysilane (KH-570), and added to the synthetic prepolymer PGEA, formulated as UV nanocomposite coating.By scanning electron microscopy (SEM) observation, it was found that the dispersion of modified nano-SiO2 was better when its content of the coating was less than 5%. Scanning atomic force microscope (AFM) observation showed that the surface of curing film was smooth. And the modified nano-SiO2 in a appropriate amount can improve the tensile strength, elongation and impact strength of the UV-curing materials.
