  • Patent number: 8217108
    Abstract: Disclosed is a novel polymeric composite including a nanoparticle filler and method for the production thereof. More particularly, the present invention provides a novel halloysite nanoparticle filler which has the generally cylindrical or tubular (e.g. rolled scroll-like shape), in which the mean outer diameter of the filler particle is typically less than about 500 nm. The filler is effectively employed in a polymer composite in which the advantages of the tubular nanoparticle filler are provided (e.g., reinforcement, flame retardant, chemical agent elution, etc.) with improved or equivalent mechanical performance of the composite (e.g., strength and ductility).

  • Publication number: 20080249221
    Abstract: Disclosed is a novel polymeric nanoparticle adhesive composite including a nanoparticle filler and method for the production thereof. More particularly, the disclosure describes the use of nanoparticle fillers, including a novel halloysite nanoparticle filler which utilizes generally cylindrical or tubular nanoparticles (e.g. rolled scroll-like shape). The filler is effectively employed in a polymer nanoparticle adhesive composite, containing the halloysite nanoparticle or other equivalent naturally occurring nanotubular filler, in which the advantages of the nanoparticle filler are provided (e.g., reinforcement, flame retardant, etc.) while maintaining or improving mechanical performance of the adhesive composite (e.g.

  • Patent number: 4755783
    Abstract: Inductive devices, i.e., transformers, coils, inductors, etc. are produced from a rolled flexible circuit. The flexible circuit is comprised of a dielectric substrate having a circuit pattern thereon. The circuit pattern is configured such that, upon rolling, one or more coils is formed thereby defining an inductor, transformer, etc. Additionally, these inductive devices may be easily shielded using a ground plane in the flexible circuit. The rolled flexible circuit may be secured in several ways including an adhesive or by using a thermoplastic bonding layer which acts to heat seal the circuit together. The inductive devices of the present invention may be wrapped or rolled about a permeable core which improves inductance. Inductor devices manufactured in accordance with the present invention have the advantages of being small, surface mountable, inexpensive to manufacture and being capable of insertion onto printed wiring boards using automated insertion equipment.
