Abstract
Carbon nanostructures can convey enhanced electrical conductivity to various substrates, while maintaining a high surface area and low density per unit area. Such substrates can provide good shielding against electromagnetic radiation over a wide range of frequencies. Electrically conductive structures can include a support layer containing a plurality of fibers having apertures defined between the fibers, and a plurality of carbon nanostructures at least partially conformally coating the fibers and bridging across the apertures defined between adjacent fibers to form a continuous carbon nanostructure layer. Each carbon nanostructure can include a plurality of carbon nanotubes that are branched, crosslinked, and share common walls with one another.
