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.

Objects produced by conventional three-dimensional printing methods are often incompletely consolidated and are not easily repaired. Printing compositions to address this issue can include a solidifiable matrix and a microwave absorber dispersed in the solidifiable matrix. The microwave absorber can be a plurality of carbon nanostructures containing a plurality of carbon nanotubes that are branched, crosslinked, and share common walls with one another. Methods for processing a three-dimensional printed object can include: providing a three-dimensional printed object formed from a printing composition containing a solidifiable matrix and a microwave absorber dispersed in the solidifiable matrix, and applying a focused input of microwave radiation to the printed object at one or more locations. Applying the microwave radiation heats the microwave absorber at the one or more locations and promotes consolidation of the printing composition within the printed object.

A method for synthesizing carbon nanotubes (CNT) comprises the steps of providing a growth chamber, the growth chamber being heated to a first temperature sufficiently high to facilitate a growth of carbon nanotubes; and passing a substrate through the growth chamber; and introducing a feed gas into the growth chamber pre-heated to a second temperature sufficient to dissociate at least some of the feed gas into at least free carbon radicals to thereby initiate formation of carbon nanotubes onto the substrate.

Carbon nanostructures free of an adhered growth substrate can include a plurality of carbon nanotubes that are branched, crosslinked, and share common walls with one another. Under applied shear, crosslinks between the carbon nanotubes in carbon nanostructures can break to form fractured carbon nanotubes that are branched and share common walls. Methods for making polymer composites from carbon nanostructures can include combining a polymer matrix and a plurality of carbon nanostructures that are free of an adhered growth substrate, and dispersing the carbon nanostructures in the polymer matrix under applied shear. The applied shear breaks crosslinks between the carbon nanotubes to form a plurality of fractured carbon nanotubes that are dispersed as individuals in the polymer matrix. Polymer composites can include a polymer matrix and a plurality of fractured carbon nanotubes dispersed as individuals in the polymer matrix.

Carbon nanostructures can include a plurality of carbon nanotubes that are branched, crosslinked, and share common walls with one another, thereby defining a porous space having a tortuous path within the carbon nanostructures. The porous space can be used for sequestering a range of particulate sizes from various types of substances. Separation membranes can include a separation body having an effective pore size of about 1 micron or less and providing a tortuous path for passage of a substance therethrough. The separation body can include carbon nanostructures.
