Patent number: 9734932Abstract: Metamaterials or artificial negative index materials (NIMs) have generated great attention due to their unique and exotic electromagnetic properties. One exemplary negative dielectric constant material, which is an essential key for creating the NIMs, was developed by doping ions into a polymer, a protonated poly (benzimidazole) (PBI). The doped PBI showed a negative dielectric constant at megahertz (MHz) frequencies due to its reduced plasma frequency and an induction effect. The magnitude of the negative dielectric constant and the resonance frequency were tunable by doping concentration. The highly doped PBI showed larger absolute magnitude of negative dielectric constant at just above its resonance frequency than the less doped PBI.Type: GrantFiled: April 15, 2014Date of Patent: August 15, 2017Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Keith L.

Patent number: 7521486Abstract: Fluoropolymers are made by admixing tetrafluoroethylene, hexfluoropropylene, and vinylidene fluoride; reacting the reaction admixture to generate a set of fluoropolymeric oligomers; irradiating the fluoropolymeric oligomeric precursor admixture (preferably with electron beam radiation) to form free radical sites on individual fluoropolymeric oligomers of the set and generate thereby a set of free radical oligomer derivatives in the fluoropolymeric oligomeric precursor admixture; and reacting the fluoropolymeric oligomeric precursor admixture to derive the fluoropolymer compound from the free radical oligomer derivatives. In a second approach, fluoropolymers are made by admixing tetrafluoroethylene, hexfluoropropylene, and vinylidene fluoride and irradiating the admixture.Type: GrantFiled: May 14, 2007Date of Patent: April 21, 2009Assignee: Freudenberg-NOK General PartnershipInventor: Edward Hosung Park
