NOVELTY - Antibacterial toughened film comprises a toughened film body and an antibacterial coating on the side of the toughened film body away from the screen. The antibacterial coating includes 100 pts. wt. glass resin, 4-8 pts. wt. modified nano-titanium dioxide and 1-3 pts. wt. curing agent. The modified nano-titanium dioxide preparation method includes soaking the nano-graphene oxide in volatile oil, ultrasonically vibrating, taking out, and drying naturally to obtain modified nano-graphene oxide. The nano silicon dioxide, nano titanium dioxide and modified nano graphene oxide are mixed uniformly, and ball milled at a speed of 100-400rad/min for 1-4 hours to obtain mixture A. The mixture A is added to a hydrogen peroxide solution with a mass concentration of 10-20 wt.%, vibrate ultrasonically, filtered and freeze-dried to obtain modified nano titanium dioxide. USE - Antibacterial toughened film.
