Interfacial-bubbling-induced nondestructive expansion to reconstruct superstrong and multifunctional carbon nanotube fibers

The severe challenge in ordering carbon nanotubes (CNTs) has become one of the key obstacles in developing high performance CNT fibers. Herein, a nondestructive straightening and multifunctionalization strategy is developed based on an interfacial-bubbling-induced expansion to CNT networks. By activating an electrolysis process in an acid solution, hydrogen bubbles are generated and evolved within the interior of CNT network, leading to an...
