Sustainable epoxy composite applications of graphene produced via electrochemical exfoliation Available to Purchase

In this study, we are the first to use electrochemically exfoliated graphene (EEG) as a filler to enhance the properties of waste jute fiber/epoxy (E-J) composites. The molecular structure of EEG nanoparticles was characterized using X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and thermogravimetric analysis. Subsequently, E-J and waste jute fiber/epoxy graphene E-J-G hybrid composites were developed, and their mechanical properties (MP) was evaluated and compared with that of neat epoxy. Results showed that incorporating graphene significantly improved the MP of the composites. The tensile strength and Young’s modulus of E-J-G increased by 5% and 75%, respectively, compared with E-J. The hardness of E-J and E-J-G samples increased by 38% and 79%, respectively, compared with neat epoxy. Both E-J and E-J-G composites exhibited notable water absorption. Produced from epoxy, graphene, and waste jute fibers, the E-J-G composite combines strong mechanical properties with environmental friendliness, enabling low-cost production using recycled jute. Its lightweight nature and high strength allow it to be used in airplane and helicopter fuselages, wings, and car parts, improving fuel efficiency and reducing emissions. In addition, because the graphene additive enhances the material’s electrical conductivity, it has potential applications in surfaces that dissipate static electricity, electromagnetic shielding, and sensor devices.
