One important application of carbon nanostructures (nanotubes, graphene) is in the field of

nanocomposites, aiming synergistic effects and novel properties. Different kind of carbon-

based nanocomposites with polymers, metals, inorganic materials, gels, among other classesof materials have described in the last years, resulting in novel and fascinating materials with

tunable electrical, magnetic, mechanical, chemical and optical properties arising from the

nanoscale coupling. This talk will be focused on some aspects of the experience acquired by

our research group on the development of novel route to synthesize carbon nanotubes and

graphene, as well as their different nanocomposites with conducting polymers (polyaniline,

polythiophene), natural rubber, metal nanoparticles (gold, platinum), Prussian blue, amongothers. Results related to the application of the nanocomposite materials as transparent

electrodes, photovoltaic devices, biosensors, gas sensors, SERS substrates and fuel cells willbe also demonstrated and discussed.
