Recent developments in natural rubber nanocomposites containing graphene derivatives and its hybrids

Graphene (GE) is a popular two-dimensional material in the area of material science and has gained much interest in the polymer nanocomposites in the last few decades because of its outstanding characteristics, such as mechanical, optical and electrical properties. Reduction or functionalization of graphene oxide (GO) into reduced graphene oxide (RGO) is the most recognized way to synthesize graphene due to the difficulty in getting graphene from natural graphite by direct exfoliation. Insertion of these graphene derivatives into natural rubber (NR) has led to the fabrication of conductive polymer nanocomposites , which in turn offer application in various fields including, super capacitors, electromagnetic interference shielding, sensors, etc. Moreover, GO and RGO is capable of enhancing the thermal, mechanical and gas barrier properties of NR matrix. This article gives an elaborative account on reinforcement of graphene, GO, RGO and their hybrids in NR as well as their applications. In addition to this, we have extended the discussion to NR/graphene/graphene derivative based blend nanocomposites. • This review gives an insight into the structure of graphene and related materials. • Reinforcement of graphene, GO, RGO and its hybrids in NR is discussed. • Details the properties of graphene and its derivatives based NR blends and composites. • Applications of NR/graphene derivatives and its hybrids are summarized in a comprehensive way.
