摘要： A method for making an antimicrobial composite film can include forming a first coating layer by applying a first coating material on a substrate and forming a second coating layer by applying a second coating material on the first coating layer. The first coating material can comprise a first resin. The second coating material can comprise an antimicrobial material in a second resin or a dispersion. The first coating material can have a lower concentration of the antimicrobial material than the second coating material. The first and second coating layers can cooperatively define a composite film. The antimicrobial material can be asymmetrically dispersed in the composite film such that the antimicrobial material is concentrated closer to the outer surface of the composite film than to the inner surface of the composite film.
