Abstract
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.
