Raman Analysis of Graphene/PANI Nanocomposites for Photovoltaic

The nanocomposites based on graphene are single- or few-layer platelets that can be produced in bulk quantities by the in-situ polymerization method. Indeed, graphene is firstly added to a solution of the monomer. The polymerization is initiated either by heat or radiation. With this technique, a variety of polymeric nanocomposites have been prepared using the different types of graphene based nanofillers. Solution mixing techniques have been shown to represent the most effective for the dispersion of graphene nanosheets in polymers, in order to manufacture new high nanocomposite systems performance. In this experimental work, we report the synthesis and characterisation using Raman spectrometer of PANI and graphene/PANI. We study the vibrational properties of polyaniline (PANI) and graphene/PANI. We find a Charges/Energy Transfer in these promising materials, the graphene/PANI nanocomposites.
