Process and solution for preparing a surface with bacteriostatic and bactericidal activity, surface thus prepared and uses thereof

Abstract

A method for conferring bacteriostatic or bactericidal properties on a surface of an object, comprising: (a) putting the surface into contact with an aqueous solution comprising an ionene-type polymer functionalised by at least one radically polymerisable function, an organic compound with two radically polymerisable functions, an organic compound with three radically polymerisable functions and a photoinitiator, (b) subjecting the surface coated with the aqueous solution to irradiation by means of which a radical polymerisation is initiated and a grafted three-dimensional polymer network comprising ionene-type polymers is obtained. The aqueous solution and the object thus obtained as well as uses thereof in particular for preparing protective garments, for packaging and/or storing fresh food products but also for purifying or decontaminating a solution or a surface.
