A review on preparation, properties and applications of graphene composites

Abstract

The flexible and bending materials technology is focusing on graphene-based materials. A popular technique for its production is chemical vapour deposition. Raman spectroscopy indicated its high quality; oxidation experiments demonstrate its substantial impermeability, and scanning electron microscopy reveals that the films are continuous over broad areas. Due to its unique properties, such as mechanical, electrical, and optical characteristics and highly readily functionalizable derivatives, graphene has emerged as a perfect candidate for the realisation of flexible electronics. Biomedical assistance, membranes, flexible wearable sensors, actuators, electronics, etc, show great promise for using graphene-based materials and their composites. This study delves into the synthesis methods of graphene composites to explore their various applications and overcome technological problems. It explores the discoveries of better mechanical characteristics and conductivity, providing insight into the future of advanced materials. The findings show that graphene and its derivatives can create nanocomposites with various polymer matrices. Graphene varieties, including pristine graphene, graphene oxide, and reduced graphene oxide, were introduced in our study. This study also investigates nanocomposites containing multiple graphene, inorganic, and polymeric components, including polymer/GR, activated carbon/GR, metal oxide/GR, metal/graphene, and carbon fibre/GR.
