The multilevel antimicrobial polymeric colloids as functional additives for latex coating are latex-based coatings with multilevel antimicrobial polymeric colloidal particles incorporated therein to provide antimicrobial properties. Each multilevel antimicrobial polymeric colloidal particle includes a polymer scaffold and at least one antimicrobial polymer carried on the polymer scaffold, such that the polymer scaffold and the at least one antimicrobial polymer form a hollow colloidal particle. As a non-limiting example, the polymer scaffold may be polyvinyl alcohol (PVA). As a further non-limiting example, the at least one antimicrobial polymer may be a combination of polyethyleneimine (PEI) and polyhexamethylene biguanide (PHMB). Each multilevel antimicrobial polymeric colloidal particle may also contain an antimicrobial core within the hollow colloidal particle.
