Abstract
A method of manufacturing an anti-counterfeit ink is provided. A tungsten oxide nanowire is provided. A hydrophilic treatment is performed to the tungsten oxide nanowire to form a tungsten oxide nanowire with hydrophilicity. The tungsten oxide nanowire with hydrophilicity and an ink are mixed to form an anti-counterfeit ink.
Claims7
