dc.description.abstract |
This letter reports on nucleation and growth of graphene foliates protruding from
the sidewalls of aligned carbon nanotubes (CNTs) and their impact on the electrochemical
double-layer capacitance. Arrays of CNTs were grown for different time intervals,
resulting in an increasing density of graphene foliates with deposition time. The
samples were characterized using electrochemical impedance spectroscopy, scanning
electron microscopy, and transmission electron microscopy. Both low and high frequency
capacitance increased with increasing foliate density. A microstructural classification
is proposed to explain the role of graphene edges, three-dimensional organization,
and other features of hybrid carbon systems on their electrochemical properties. ©
