▎ 摘  要

NOVELTY - Preparation of graphene-based fibers involves (A) releasing an aqueous graphene oxide suspension with at least 20 g/L graphene oxide into an ionic solution through a nozzle, to form a longitudinal fiber, (B) separating fiber from ionic solution and (C) contacting the fiber with a solvent having a polarity higher than water. USE - Preparation of graphene-based fibers. Uses include but are not limited to energy, biotechnology, electrical and composite applications. ADVANTAGE - The method efficiently produces graphene-based fibers with excellent flexibility, mechanical strength, and fiber density, and reduced or no electrical conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) aqueous graphene oxide suspension; and (2) system for obtaining graphene-based longitudinal fibers.
