The dispersion of graphene in conductive epoxy composites investigated by Raman spectroscopy

The two-dimensional structure and unique properties make graphene an efficient candidate to strengthen the electrical and mechanical characteristics of polymer composites. The effectiveness for improving the electrical property of composites strongly depends on the size, electrical conductivity and dispersion of graphene fillers in polymer matrix. Here, we demonstrate that Raman spectroscopy can be used to study the dispersion of conductive...
