Tóm tắt

 This invention relates to methods for chemically grafting and attaching ceragenin molecules to polymer substrates
  methods for synthesizing ceragenin-containing copolymers
  methods for making ceragenin-modified water treatment membranes and spacers
  and methods of treating contaminated water using ceragenin-modified treatment membranes and spacers. Ceragenins are synthetically produced antimicrobial peptide mimics that display broad-spectrum bactericidal activity. Alkene-functionalized ceragenins (e.g., acrylamide-functionalized ceragenins) can be attached to polyamide reverse osmosis membranes using amine-linking, amide-linking, UV-grafting, or silane-coating methods. In addition, silane-functionalized ceragenins can be directly attached to polymer surfaces that have free hydroxyls.
