Graphene and graphene-based materials have attracted significant attention due to their excellent electrical, mechanical, and optical properties, as well as the ease of functionalization of their derivatives. Graphene, graphene oxide (GO), and reduced graphene oxide (rGO) have been used to develop composite materials with conducting polymers, metal matrices, carbon-carbon matrices, and natural fibers. These graphene-based composite materials have potential applications in energy-harvesting systems, clean-energy storage devices, and wearable/portable electronics, due to their superior mechanical strength, conductivity, and thermal stability. The paper provides a comprehensive review of the most recent progress in the synthesis and applications of these graphene-based composite materials. The review also summarizes the current difficulties and challenges in the development of graphene-based technologies. The paper aims to provide a useful database for further innovation and advancement of graphene-based composite materials
