ABSTRACT
This chapter offers a consolidated review of work on state-of-the-art thermoelectric composites. It focuses on graphene-based polymeric composites as upcoming/new generation TE materials. Graphene is a unique class of carbon having a two-dimensional sheet which is just one atom thick. Graphene nanoribbons are basically the narrow stripes of graphene having a lattice of hexagonal carbon with quasi-one-dimensional geometry. Some number of literatures has been focused to cover synthesis of graphene-based metal oxide for various applications such as a catalyst, anode material for lithium ion battery, solar cell, fuel cell, etc. Selected area electron diffraction pattern and high-resolution transmission electron microscopy were carried out to examine the quality of nano iron oxide decoration over graphene layer. A green/ecofriendly method has been developed for the preparation of graphene-metal oxide nanocomposite preparation. Synthesis of graphene metal oxide nanocomposites (GMNC) is very simple. Ecofriendly techniques like ultrasonication and microwave irradiation have been used to synthesize GMNCs.
