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.
