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.
A transparent, water resistant, antimicrobial and antiviral waterborne coating composition comprising a synthesized polymer, wherein the synthesized polymer comprises a vinyl group monomer, an acrylate monomer, a polymerizable quaternary ammonium compound (QAC) comprising an acrylate group and a cationic group a silane monomer, an adhesion monomer and an emulsification monomer, wherein the silane monomer is connected with the QAC for ensuring the anti-microbial and antiviral ability of the QAC;
