Abstract: An antibacterial paper comprises a paper substrate, wherein at least one external surface of the paper substrate is coated with an antibacterial coating layer containing titanium dioxide particles uniformly distributed therein, the average particle size of the titanium dioxide particles is less than or equal to 200 nanometers (nm), and the mass percentage of the titanium dioxide particles contained in the antibacterial coating layer is more than or equal to 5% of the mass of the antibacterial coating layer.

Abstract: Process for making an antibacterial coating includes the following steps. A solution containing titanium dioxide particles and a dispersant is prepared. A mechanical stirring method is employed to prepare a preliminary titanium dioxide dispersed solution. An ultrasonic agitation method is employed to prepare a nanometer titanium dioxide dispersed solution, an average particle size of the titanium dioxide particles being less than or equal to 200 nanometers. Lastly, the nanometer titanium dioxide dispersed solution is mixed with a papermaking coating to prepare an antibacterial coating.
