Hybrid nanomaterials are interesting class of materials owing to their multifunctionality tailored at the interface of the constituents. Graphene has attracted a great deal of attention attributed to extraordinary physical properties. Likewise, pi-conjugated polymers serve as playground for supramolecular nanostructures and as hybrids and nanocomposites. This work is centered at the design and development of ‘smart’ hybrid nanocomposites from functional nanobuilding blocks of graphene and its derivatives and electrochemically polymerized conducting polymers (polypyrrole and poylaniline) via layer-by-layer approach. Here we investigate their structural and physical properties using complementary techniques including scanning and transmission electron microscopy, atomic force microscopy, room temperature electrical property and resonance Raman spectroscopy with mapping, to determine surface morphology, surface roughness / uniformity / (in)homogeneity, nanoscale (amorphous versus semicrystalline) structure, and spring constant and elasticity distribution to establish microscopic structure- processing-property relationship. The experimental findings elucidate the optimized properties of synthesized hybrids for space and energy industries.
