Preparation and characterization of ultraviolet-curable nanocomposite coatings initiated by benzophenone/n-methyl diethanolamine

摘要

A series of ultraviolet-curable nanocomposite coatings were prepared with condensed nanosilica particles and with benzophenone/n-methyl diethanolamine as the initiator. The nanosilica that incorporated into the nanocomposites did not aggregate even when the nanosilica concentration was as high as 22.5. Adding nanosilica increased the curing speed, thermal stability, and ultraviolet shielding properties of the nanocomposites without reducing the transparency of the ultra viol et-curing coatings.
