  • Patent number: 9734932
    Abstract: 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.

    Abstract: An article is provided that includes a polymeric fiber that has an excess number of surface active reactive moieties relative to the number of surface reactive moieties found on the fiber in a native state. A particle is bonded covalently to the fiber through an intermediate coupling agent. Multiple particles can be covalently bonded to the fiber, the multiple particles can be bonded uniformly or asymmetrically around the fiber diameter. A process for modifying a fiber includes creating surface activated reactive moieties thereon. The activated fiber is then exposed to a liquid solution containing a coupling agent to form a covalent bond. The coupling agent is also reacted with a particle in a liquid solution to form a covalent bond between the coupling agent and the particle. The coupling agent is covalently bonded to either a particle and then bonded to the fiber, or vice versa.

    Abstract: The present invention is directed to a composition of adhering together first and second materials. The composition features a multi-functional reactive compound that includes a backbone group and first and second functional groups; a cross-linker, and a catalyst. The first functional group is responsive to a first actinic energy to form cross-linked molecules and to adhere a subset of the cross-linked molecules to the first material. The second functional group is responsive to a second actinic energy, differing from the first actinic energy to adhere to the second material.

  • Patent number: 7521486
    Abstract: 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.
