  • Publication number: 20110027518
    Abstract: This invention is an acoustic device protected by an acoustically transparent low water permeability encapsulant made from an acoustically clear polymer such as polyurethane. High aspect ratio clay nanoparticles are positioned in the substrate in overlapping layers with layers of the substrate interposed. The invention also provides a method for forming an acoustically transparent low permeability encapsulant about an acoustic device. The method includes treating high aspect ration clay nanoparticles to make them organophilic. The treated nanoparticles are then mixed in a polymer resin in such a way as to form an intercalated mixture. A curing agent is added to the mixture, and the mixture is allowed to set. When set the resulting intercalated mixture produces an acoustically clear, low permeability polymer coating.

  • Publication number: 20110001398
    Abstract: A single wall carbon nanotube (SWCNT) film electrode (FE), all-organic electroactive device systems fabricated with the SWNT-FE, and methods for making same. The SWCNT can be replaced by multi-wall carbon nanotubes or few wall carbon nanotubes. The SWCNT film can be obtained by filtering SWCNT solution onto the surface of an anodized alumina membrane. A freestanding flexible SWCNT film can be collected by breaking up this brittle membrane. The conductivity of this SWCNT film can advantageously be higher than 280 S/cm. The EAP actuator layered with the SWNT-FE shows a higher electric field-induced strain than an EAP layered with metal electrodes because the flexible SWNT-FE relieves the restraint of the displacement of the polymeric active layer as compared to the metal electrode. In addition, if thin enough, the SWNT-FE is transparent in the visible light range, thus making it suitable for use in actuators used in optical devices.

  • Patent number: 7371457
    Abstract: The present invention is for particulate compositions and methods for producing them that can absorb or scatter electromagnetic radiation. The particles are homogeneous in size and are comprised of a nonconducting inner layer that is surrounded by an electrically conducting material. The ratio of the thickness of the nonconducting layer to the thickness of the outer conducting shell is determinative of the wavelength of maximum absorbance or scattering of the particle. Unique solution phase methods for synthesizing the particles involve linking clusters of the conducting atoms, ions, or molecules to the nonconducting inner layer by linear molecules. This step can be followed by growth of the metal onto the clusters to form a coherent conducting shell that encapsulates the core.
