Title (EN) METHOD FOR ACTIVATING THE SURFACE OF POLYMER MATERIALS
(FR) PROCÉDÉ D'ACTIVATION DE LA SURFACE DE MATÉRIAUX POLYMÈRES
(PT) MÉTODO DE ATIVAÇÃO DA SUPERFÍCIE DE MATERIAIS POLIMÉRICOS
Abstract:
(EN) The present invention describes a method for chemically and/or biologically activating the surface of originally inert polymer materials. Polymer surface activation occurs exclusively by means of the physical incorporation of at least one linear long-chain compound containing at least one reactive terminal group into the inert polymer, in the presence of at least one solvent.
(FR) La présente invention concerne un procédé pour l'activation chimique et/ou biologique de la surface de matériaux polymères initialement inertes. L'activation de la surface polymère se produit exclusivement lors de l'incorporation physique d'au moins un composé linéaire à chaîne longue présentant au moins une terminaison réactive de la part du polymère inerte, en présence d'au moins un solvant.
(PT) A presente invenção descreve um método para ativar quimicamente e/ou biologicamente a superfície de materiais poliméricos originalmente inertes. A ativação da superfície polimérica ocorre exclusivamente por meio da incorporação física de pelo menos um composto linear de cadeia longa contendo pelo menos uma terminação reativa por parte do polímero inerte, na presença de pelo menos um solvente.
