TL;DR: In this paper, the authors demonstrate the facile and direct spinning of three-ply core-sheath graphene fiber supercapacitors with thin and continuous wrinkling gel electrolyte interlayer by a wet spinning approach through coaxial three-channel spinneret.

TL;DR: In this article, a polyaniline (PANI) hydrogel was applied to a porous carbon nanotube (CNT) film to make a symmetric all-solid-state supercapacitor with a favorable specific capacitance of 315 F g−1 and relatively high cycling stability.

TL;DR: An efficient approach for preparing super-tough yarns of reduced graphene oxides via the in situ twisting of multiplied graphene oxide fibres during fibre extrusion and coagulation, followed by chemical reduction and drying is demonstrated.

TL;DR: In this article, a method for the preparation of multi-strand graphene oxide fiber is presented. But the preparation method comprises the steps: (1) putting a graphene oxide spinning solution with a certain concentration into a spinning device, then evenly extruding the spinning solution into a coagulation bath from a spinning nozzle on a spinning head, and rotating the spinning head while extruding, to realize preparation and twisting of a multistrand GORO fiber; and (2) reducing the multistrand GOROO fiber after twisting, to obtain a twisted multistand
