摘要： An electrically conductive composite material includes metallic nanostrands distributed throughout a matrix constructed of a polymer, ceramic, or elastomer. The nanostrands may have an average diameter under four microns and an average aspect ratio over ten-to-one. Larger fibers may also be included to enhance electrical conductivity or other properties. The nanostrands and/or fibers may be magnetically oriented to enhance electrical conductivity along one direction. A pressure sensor may be formed by utilizing an elastomer for the matrix. Electrical conductivity through the composite material varies in proportion to deflection of the elastomer. A composite material may be applied to a surface as an electrically conductive paint. Composite materials may be made by cutting a blank of the nanostrands to the desired shape, inserting the matrix, and curing the matrix. Alternatively, a suspension agent may first be used to dispose powdered nanostrands in the desired shape.

摘要： An electromagnetically active composite has an electrically-nonconductive host matrix and electrically-conductive nanostrand bodies embedded in a substantially uniform distribution throughout the host matrix. Each of the nanostrand bodies comprises a volume containing at least one nanostrand of filamentary metal. Adjacent nanostrand bodies that are sufficiently mutually proximate will interact electromagnetically with each other. The filamentary metal of the one or more nanostrands in each of the nanostrand bodies occupies a deminimus fraction of the overall volume occupied by the at least one nanostrand that comprises each of the nanostrand bodies. The filamentary metal is chosen from among the group of metals that includes nickel, nickel aluminides, iron, iron aluminides, alloys of nickel and iron, and alloys of nickel and copper. Individual nanostrands of the nanostrand bodies have an average diameter in a range of from about 10 nanometers to about 4000 nanometers, and the average diameter of the nanostrand bodies is in a range of from about one micron to about 3000 microns.

摘要： The electrical resistance of active cathodic and anodic films may be significantly reduced by the addition of small fractions of conductive additives within a battery system. The decrease in resistance in the cathode and/or anode leads to easier electron transport through the battery, resulting in increases in power, capacity and rates while decreasing joules heating losses.

摘要： An electrically conductive paint/caulk is disclosed that may be applied by spraying, rolling, and/or brushing using conventional techniques/may be dispensed from a tube. The electrically conductive paint/caulk has a plurality of metal-coated fibers precision chopped to short lengths, optionally a plurality of conductive filament structures having a high-aspect ratio, and a polymer base. The metal-coated fibers and optional conductive filament structures are dispersed uniformly within the polymer base to create a complex electron transport system facilitating conductivity sufficient for a full range of electromagnetic properties including electrostatic dissipation, electrostatic discharge, and shielding. The complex electron transport system created facilitates the full range of electromagnetic properties with lower loadings of conductors, reduces viscosity, and the additional unloaded portion of paint/caulk receives other multifunctional additives.
