    摘要: Provided is a new supercapacitor electrode material, comprising multiple interpenetrating networks of nanowires. More specifically, an interpenetrating network of metal oxide nanowires and an interpenetrating network of electrically conductive nanowires may form a composite film having a hierarchal porous structure. This hierarchically porous, interpenetrating network structure can provide the composite film with high capacitance, electrical conductivity and excellent rate performance. The present invention can be generalized towards other capacitor composites, opening a new avenue for a large spectrum of device applications.

    摘要: A mesoporous carbon film having a unimodal pore structure comprises a film of carbon defining an open network of interconnected primary pores arrayed in a uniform, random manner throughout the film. The pores in the film have an average pore diameter in the range of about 2 to about 3 nm, and the diameters of the pores have a substantially unimodal pore diameter distribution. Not more than about 20 % of the pores in the film have a diameter of less than about 1 nm. The mesoporous carbon films can be prepared by depositing a thin film of an aqueous sol-gel composition comprising a polysiloxane gel precursor, and a water soluble carbohydrate onto a substrate, heating the thin film to carbonize the carbohydrate and form a carbon/silica nanocomposite film, and removing the silica from the carbon/silica nanocomposite film to provide a continuous mesoporous carbon film. Suspending colloidal silica in the aqueous sol-gel composition prior to depositing the thin film on the substrate affords a mesoporous carbon film having a hierarchical, bimodal pore structure, which includes spherical secondary pores randomly distributed throughout the film and interconnecting with the network of primary pores.

    摘要: A thermoelectric material comprises two or more components, at least one of which is a thermoelectric material. The first component is nanostructured, for example as an electrically conducting nanostructured network, and can include nanowires, nanoparticles, or other nanostructures of the first component. The second component may comprise an electrical insulator, such as an inorganic oxide, other electrical insulator, other low thermal conductivity material, voids, air-filled gaps, and the like. Additional components may be included, for example to improve mechanical properties. Quantum size effects within the nanostructured first component can advantageously modify the thermoelectric properties of the first component. In other examples, the second component may be a thermoelectric material, and additional components may be included.
