Abstract
Green routes based on non-covalent functionalization approaches have been developed to prepare surface-functionalized graphene oxide (GO) nanosheets with bioactive compounds such as polyphenols. Amongst them, gallic acid (GA) and tannic acid (TA) are known to have strong antioxidant activity and can act as reducing and stabilizing agents of GO, resulting in reduced graphene oxide (rGO) derivatives with improved properties such as solubility in organic solvents, thermal stability and mechanical performance. Polyphenols act as crosslinkers between the GO nanosheets, leading to higher thermal resistance and improved stiffness, strength and toughness. A synergistic effect of both GO and polyphenols on inhibiting bacterial growth has also been found. The Π-Π and H-bonding interactions are believed to be the reason for the improved properties. The combination of bioactive molecules and carbon nanomaterials is a useful method towards the development of green, low-cost, biodegradable nanocomposites to be used in biomedicine, energy storage devices or other enviromentally friendly applications.
