摘要 |
<p>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.</p> |
