Fabrication of Ultralong Hybrid Microfibers from Nanosheets of Reduced Graphene Oxide and Transition‐Metal Dichalcogenides and their Application as Supercapacitors

Two‐dimensional materials have attracted increasing research interest owing to their unique electronic, physical, optical, and mechanical properties. We thus developed a general strategy for the fabrication of ultralong hybrid microfibers from a mixture of reduced graphene oxide and transition‐metal dichalcogenides (TMDs), including MoS2, TiS2, TaS2, and NbSe2. Furthermore, we prepared fiber‐based solid‐state supercapacitors as a proof‐of‐concept application. The performance of thus‐prepared supercapacitors was greatly improved by the introduction of the TMDs.
