Carbon nanomaterials, like graphene oxide (GO) and reduced graphene oxide
(rGO), have attracted great interest during last few years because of their
potential applications in electrochemical devices, energy storage, catalysis,
enzyme adsorption, drug delivery, biosensors, etc. Recently, it has been
observed that the performance of some devices is increased when using threedimensional
structures made of nanomaterials due to an increase of active
material per exposed area. The current challenge is to obtain self-sustained
three-dimensional materials made with nanostructures, like GO or rGO,
preserving their nanometric properties in macroscopic structures to maximize
their performance and ease their manipulation during device fabrication. Then,
the control achieved on the structure in these macroscopic assemblies is the key
step to achieve better performance. The development of new methodologies to
obtain macrostructures based on nanostructures is highly demanded, some of
the current methodologies include self-assembly techniques, template-assisted
methods, direct deposition on conductive substrates, covalent linkage, etc.,
which focus on obtaining structured materials with certain morphologies,
structures and properties. In this study, a self-sustained three-dimensional
structure was obtained using microparticles as template and GO by combining
template assisted methods and self-assembly techniques. Self-assembly of
graphene oxide on the particles was controlled to achieve a uniform coating.
The main advantages of using a template is the control of the shape and size
distribution of the porous structure in the final self-sustained structure leading
to obtain three-dimensional porous materials based on GO or rGO.
