Title (EN) METHOD OF APPLYING CHEMICAL CHARGE MODIFIERS TO A SUBSTRATE AND ARTICLE THEREOF
(FR) PROCEDE D'APPLICATION DE MODIFICATEURS DE CHARGES CHIMIQUES A UN SUBSTRAT ET ARTICLE EN RESULTANT
Abstract:
(EN) A method of applying chemical charge-modifiers to a permeable sheet including the steps of: providing a permeable sheet having a plurality of individual exposed surfaces, at least a portion of which having relatively low surface energies; providing an aqueous solution containing amphiphilic macromolecules, the solution having a relatively high surface tension; contacting the solution containing amphiphilic macromolecules under shear stress conditions with the permeable sheet so that at least a portion of the amphiphilic macromolecules are adsorbed onto at least some individual exposed surfaces to form a coated permeable sheet; and contacting the coated permeable sheet with a solution containing chemical charge modifiers to incorporate chemical charge modifiers onto at least a portion of the amphiphilic macromolecules. A chemically charge-modified permeable sheet composed of: a permeable sheet having a plurality of individual exposed surfaces, at least a portion of which having a surface energy of less than about 45 dynes per centimeter; amphiphilic macromolecules adsorbed onto at least some individual exposed surfaces; and chemical charge modifiers incorporated onto at least a portion of the amphiphilic macromolecules.
(FR) L'invention porte sur un procédé d'application de modificateurs de charge chimique à une feuille perméable comportant les étapes suivantes: prendre une feuille perméable présentant une série de surfaces exposées individuelles dont une partie au moins présentent une des énergies superficielles relativement basses; prendre une solution aqueuse comportant des macromolécules amphiphiliques et présentant une tension superficielle relativement élevée; mettre en contact ladite solution dans des conditions de contraintes de cisaillement avec la feuille perméable de manière à ce qu'une portion au moins des macromolécules amphiphiliques soient adsorbées sur au moins certaines des surfaces pour former une feuille perméable revêtue puis à: mettre en contact la feuille perméable ainsi traitée avec une solution contenant des modificateurs de charge chimique pour incorporer lesdits modificateurs dans au moins une partie des macromolécules amphiphiliques. L'invention porte également sur une feuille perméable à charge modifiée comportant une feuille perméable présentant une série de surfaces exposées dont une partie au moins présentent une énergie superficielle de moins de 45 dynes par cm; des macromolécules amphiphiliques adsorbées sur au moins certaines des surfaces individuelles exposées; et des modificateurs de charge chimique incorporés à au moins une partie des molécules amphiphiliques.
