ABSTRACT:
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.
