| Zusammenfassung: | A method of making a water filter includes formulating a solution comprising a polymer, an adsorbent, and a first solvent, the polymer being soluble in the first solvent, casting the solution onto a substrate to form a thin film, dissolving the first solvent in a second solvent to precipitate the polymer out of solution, removing the thin film from the substrate, and rolling the thin film to form a cylindrical filter.
Procédé de fabrication d'un filtre à eau consistant à formuler une solution comprenant un polymère, un adsorbant et un premier solvant, le polymère étant soluble dans le premier solvant, couler la solution sur un substrat pour former un film mince, dissoudre le premier solvant dans un second pour précipiter le polymère hors de la solution, retirer le film mince du substrat et laminer le film mince pour former un filtre cylindrique. |
