摘要： A process for imparting bacteriostatic or bactericidal properties to the surface of an object, which consists in (a) providing an object of which the surface bears groups comprising at least one oxygen atom; (b) applying, to the surface provided in step (a), a coating based on polymers of polydopamine or a derivative thereof carrying at least one function —Y, where Y is a halogen atom or a function —N(R11)(R12) in which R11 and R12 are identical or different and are a hydrogen atom, an optionally substituted alkyl group or an optionally substituted aryl group; and (c) contacting the coated surface obtained after step (b) with a solution containing at least one dihalogen and at least one diamine at a temperature greater than ambient temperature, whereby a polyionene polymer-based coating is grafted covalently to said coated surface obtained after step (b).
