Graphene and its derivatives, with outstanding characteristics corresponding to smart electrical and mechanical properties, received greater attention of researchers to explore novel materials with potential applications. Recently, graphene based novel nanocomposite materials and conducting polymers such as polyaniline (PANI), polypyrrole (PPY), polyethyldioxythiophene (PEDOT), polythiophene (PTH) and their derivatives are widely utilized as active materials in gas sensing because of their distinctive electrical conductivity, redox property, and optimal working capacity at room temperature. The sensing performance is enhanced by combining these two materials, namely, pure graphene and conducting polymers. This may be attributed to the enhanced specific area of the nanocomposites. The general methods of preparation of nanocomposite preparation involves in situ polymerization, electropolymerization, resolution mixing, self-assembly approach, etc., The effective gas sensing performance of those prepared nanocomposites has been established by various researchers. In this point of view, recent efforts and applications of graphene and conducting polymer nanocomposites for sensing are discussed in this review paper.
