From our extensive work with polymeric materials, we have developed a proprietary, nanotechnology-based family of polymers and methodologies for their synthesis and fabrication. We are able to manufacture, with standard equipment and processes, novel nanostructured ion-containing polymers, also known as ionomers or polyelectrolytes. Dais has demonstrated success in the design and synthesis of a new class of simple and versatile ionomers that have a wide array of useful characteristics. These include excellent ion conduction, ion-exchange capability, moisture transfer, and anti-fouling properties. Our materials are typically derived from the sulfonation of styrene-containing block copolymers. The block copolymers phase-separate on a nanoscopic scale forming nano-domains that are interconnected, affording excellent ion conductivity and water transport. Our polymers can be covalently crosslinked and can be compounded with a variety of other polymers and/or inorganic fillers, and thus are the basis for a broad class of materials with unique properties and applications.

Dais has been issued six United States patents, and have additional United States patent applications pending, with respect to several unique forms of our nanostructured polymer membranes, their creation and mechanisms of operation, and application-related protection for use of these novel materials in value-added products.
