A system that receives nanomaterials, forms nanofibrous materials therefrom, and collects these nanofibrous materials for subsequent applications. The system is coupled to a chamber that generates nanomaterials, typically carbon nanotubes produced from chemical vapor deposition, and includes a mechanism for spinning the nanotubes into yarns or tows. Alternatively, the system includes a mechanism for forming non-woven sheets from the nanotubes. The system also includes components for collecting the formed nanofibrous materials. Methods for forming and collecting the nanofibrous materials are also provided.

A system that receives nanomaterials, forms nanofibrous materials therefrom, and collects these nanofibrous materials for subsequent applications. The system include a housing coupled to a synthesis chamber within which nanotubes are produced. A spindle may extend from within the housing, across the inlet, and into the chamber for collecting nanotubes and twisting them into a yarn. A body portion may be positioned at an intake end of the spindle. The body portion may include a pathway for imparting a twisting force onto the flow of nanotubes and guide them into the spindle for collection and twisting into the nanofibrous yarn. Methods and apparatuses for forming nanofibrous are also disclosed.

The present invention relates to systems and methods for generating nanoscopically aligned carbon nanotubes in yarns, tapes and sheets. Some embodiments relate to methods and systems to allow in situ alignment of the tubes within the growth chamber. In particular, processes for in situ alignment include: (1) gas flow alignment using gas lenses introduced within the reaction tube, (2) electrostatic alignment using electrostatic lenses surrounding the reaction tube, (3) gas flow alignment by convergent flow within the reaction tube, (4) placing catalysts on a fixed substrate and flowing reaction gas parallel to the substrate. Other embodiments involve post processing of the CNT material in order to align the materials once it has been produced. In particular, processes for ex situ alignment include: (1) introducing a horizontal anchor within a standard sheet system and stretching that sheet with respect to a fixed drum and (2) adding chemicals to a sheet, tape or yarn to help break electrostatic bonds and enable stretch alignment.

A conductive adapter for carrying relatively high current from a source to an external circuit without degradation is provided. The adapter includes a conducting member made from a conductive nanostructure-based material and having opposing ends. The adapter can also include a connector portion positioned on one end of the conducting member for maximizing a number of conductive nanostructures within the conducting member in contact with connector portion, so as to enable efficient conduction between a nanoscale environment and a traditional electrical and/or thermal circuit system. The adapter can further include a coupling mechanism situated between the conducting member and the connector portion, to provide a substantially uniform contact between the conductive nanostructure-based material in the conducting member and the connector portion. A method for making such a conductive adapter is also provided.
