POLY(BUTYLENE TEREPHTHALATE)/GRAPHENE COMPOSITES AND METHOD FOR PREPARING THE SAME |
摘要 |
PURPOSE: A manufacturing method of a polyurethane composite film is provided to provide a moisture-permeable and waterproof polyurethane film by absorbing anions to particle size-controlled hydroxyapatite. CONSTITUTION: A manufacturing method of a polyurethane composite film comprises: a step of manufacturing polyurethane liquid; a step of manufacturing a nanohydroxyapatite dispersion; a step of manufacturing a polyurethane/apatite composite composition by mixing the hydroxyapatite dispersion into the polyurethane liquid; a step of preparing a polyurethane composition by putting a mixture of water and organic solvent into the composite composition; a step of preparing a polyurethane composite film by film casting the polyurethane composition; and a step of absorbing silver ions by impregnating the polyurethane composite film into the silver nitrate solution.
