General Metal-Ion Mediated Method for Functionalization of Graphene Fiber
Graphene fibers (GFs)
are attractive materials for wearable electronics because of their
lightness, superior flexibility, and electrical conductivity. However,
the hydrophobic nature and highly stacked structure endow GFs similar
characteristics in nature to solid carbon fibers. Therefore, the interior
functionalization of GFs so as to achieve synergistic interaction
between graphene nanosheets and active materials thus enhance the
performance of hybrid fibers remains a challenge. Herein, a general
metal-ion mediated strategy is developed to functionalize GFs and
nanoparticles of Cu, Fe<sub>2</sub>O<sub>3</sub>, NiO, and CoO are
successfully incorporated into GFs, respectively. As proof-of-concept
applications, the obtained functionalized GFs are used as electrodes
for electrochemical sensors and supercapacitors. The performances
of thus-devised fiber sensor and supercapacitor are greatly improved
