Using ultraviolet (UV)-curable 3-(2-(methacryloyloxy)ethyl)-1-alkyl imidazoliums with different alkyl substituents as the bactericidal monomers and trimethylolpropane triacrylate as the crosslinker, highly efficient antibacterial coatings were designed and facilely prepared by a one-step UV-curing method. The differential photocalorimetry experiment showed these monomers polymerized within 120 s under UV irradiation, indicating a very good curable property. The excellent antibacterial activity of these coatings, which reached up to 99.8% ratio against Escherichia Coli, was demonstrated by a shake flask test method.
