Abstract

A polymerizable quaternary ammonium compound (QAC) including an acrylate group and a cationic group is provided. Specifically, the acrylate group is capable of polymerization so as to integrate the QAC into a macromolecular chain of a polymer through an addition polymerization for introducing antimicrobial and antiviral activities. For instance, the polymerizable QAC can be polymerized with a vinyl group monomer, an acrylate monomer, a silane monomer, an adhesion monomer and an emulsification monomer to form a synthesized polymer emulsion. The polymer emulsion can be further incorporated into a coating material to provide a transparent, water resistant, antimicrobial and antiviral waterborne coating on a substrate's surface.
