Abstract: Carbon nanotube-infused fiber materials containing substantially parallel-aligned, infused carbon nanotubes are described herein. The carbon nanotube-infused fiber materials contain a fiber material and a layer of carbon nanotubes infused to the fiber material, where the infused carbon nanotubes are aligned substantially parallel to the longitudinal axis of the fiber material and at least a portion of the substantially parallel-aligned, infused carbon nanotubes are crosslinked to each other, to the fiber material, or both. Crosslinking can occur through covalent bonding or pi-stacking interactions, for example. The carbon nanotube-infused fiber materials can further contain additional carbon nanotubes that are grown on the layer of substantially parallel-aligned, infused carbon nanotubes. Composite materials containing the carbon nanotube-infused fiber materials and methods for production of the carbon nanotube-infused fiber materials are also described herein.

Abstract: A carbon nanostructure that is free of a growth substrate can include a plurality of carbon nanotubes that are branched, crosslinked, and share common walls with one another. The carbon nanostructure can be released from a growth substrate in the form of a flake material. Optionally, the carbon nanotubes of the carbon nanostructure can be coated, such as with a polymer, or a filler material can be present within the porosity of the carbon nanostructure. Methods for forming a carbon nanostructure that is free of a growth substrate can include providing a carbon nanostructure adhered to a growth substrate, and removing the carbon nanostructure from the growth substrate to form a carbon nanostructure that is free of the growth substrate. Various techniques can be used to affect removal of the carbon nanostructure from the growth substrate. Isolation of the carbon nanostructure can further employ various wet and/or dry separation techniques.

Abstract: Processes for growing carbon nanotubes on metal substrates are described herein. The processes include depositing a catalyst precursor on a metal substrate, optionally depositing a non-catalytic material on the metal substrate, and after depositing the catalyst precursor and the optional non-catalytic material, exposing the metal substrate to carbon nanotube growth conditions so as to grow carbon nanotubes thereon. The carbon nanotube growth conditions convert the catalyst precursor into a catalyst that is operable for growing carbon nanotubes. The metal substrate can remain stationary or be transported while the carbon nanotubes are being grown. Metal substrates having carbon nanotubes grown thereon are also described.

Abstract: The present disclosure describes methods for growing carbon nanotubes on metal substrates. The methods include depositing a catalytic material on a metal substrate to form a catalyst-laden metal substrate; optionally depositing a non-catalytic material on the metal substrate prior to, after, or concurrently with the catalytic material; conveying the catalyst-laden metal substrate through a carbon nanotube growth reactor having carbon nanotube growth conditions therein; and growing carbon nanotubes on the catalyst-laden metal substrate. The catalyst-laden metal substrate can optionally remain stationary while the carbon nanotubes are being grown. The catalytic material can be a catalyst or a catalyst precursor. The catalytic material and the optional non-catalytic material can be deposited on the metal substrate from one or more solutions by, for example, spray coating or dip coating techniques.
