Title: Biofouling-resistant ceragenin-modified materials and structures for water treatment

Abstract

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.

Oil and water resistant low adhesion surface treatment and coatings

Patent Arumugam, Ganesh Kumar; Veedu, Vinod P.; Nakatsuka, Matthew

A novel omniphobic surface coating is disclosed that provides both high oil-repellency and high-water repellency to the coated surface. The coating may contain perfluoropolyether (PFPE) or a similar fluorinated or perfluorinated polymer, as well as a hardener and a catalyst. One or more surfactants or viscosifiers may also be added. Further, the coating may contain one or more functional additives, including, but not limited to, coloring agents, anti-corrosive agents, anti-fouling agents, water-repellent agents, and/or oil-repellent agents. Methods for formulating the novel omniphobic surface coating are also described. Such methods include preparing a first part of the coating, which may contain,more » « less

Use of ceragenins to create novel biofouling resistant water-treatment membranes.

Technical Report Hibbs, Michael R; Altman, Susan Jeanne; Feng, Yanshu [Brigham Young University, Provo, UT]; ...

Scoping studies have demonstrated that ceragenins, when linked to water-treatment membranes have the potential to create biofouling resistant water-treatment membranes. Ceragenins are synthetically produced molecules that mimic antimicrobial peptides. Evidence includes measurements of CSA-13 prohibiting the growth of and killing planktonic Pseudomonas fluorescens. In addition, imaging of biofilms that were in contact of a ceragenin showed more dead cells relative to live cells than in a biofilm that had not been treated with a ceragenin. This work has demonstrated that ceragenins can be attached to polyamide reverse osmosis (RO) membranes, though work needs to improve the uniformity of the attachment.more » « less

Patent Allen, Charles A.; Argyle, Mark D.; Fox, Robert V.; ...

The present invention is related to the modifying of substrates such as monofilaments, bundles of monofilaments, and fibrous structural material with a modifying agent. The modifying agent is suspended or dissolved in a supercritical fluid, near-critical fluid, superheated fluid, superheated liquid, or a liquified gas and is deposited by rapidly altering the pressure in a chamber to deposit the modifying material onto the substrate.
