A method for impregnating a polymer with a bioactive material includes preparing a bioactive metal solution having a bioactive metal, a first solvent in which the bioactive metal is insoluble and a second solvent in which the bioactive metal is slightly soluble. The method also includes soaking the polymer in the bioactive metal solution. Another method for impregnating a polymer with a bioactive material includes soaking the polymer in a swelling solvent followed by soaking the polymer in a bioactive metal solution having the bioactive metal and a solvent in which the bioactive metal is slightly soluble. A bioactive met-al-impregnated polymer is prepared by soaking a polymer in a saturated bioactive metal solution comprising a bioactive metal, a swelling solvent in which the bioactive metal is insoluble, and a second solvent in which the bioactive metal is slightly soluble.

La présente invention concerne un procédé d'imprégnation d'un polymère par un matériau bioactif, qui consiste à préparer une solution de métal bioactif contenant un métal bioactif, un premier solvant dans lequel le métal bioactif est insoluble et un second solvant dans lequel le métal bioactif est légèrement soluble. Ledit procédé consiste également à immerger le polymère dans la solution de métal bioactif. Un autre procédé permettant d'imprégner un polymère par un matériau bioactif consiste à immerger le polymère dans un solvant de gonflement puis à immerger le polymère dans une solution de métal bioactif contenant le métal bioactif et un solvant dans lequel le métal bioactif est légèrement soluble. On prépare un polymère imprégné par un métal bioactif en immergeant un polymère dans une solution de métal bioactif saturée contenant un métal bioactif, un solvant de gonflement dans lequel le métal bioactif est insoluble, et un second solvant dans lequel le métal bioactif est légèrement soluble.
