2P-131 : Preparation of graphene oxide coated glass-fiber, graphene oxide Malic acid grafted poly propylene composites for electromagnetic interference shielding application

The graphene oxide coated glass-fiber, graphene oxide Malic acid grafted poly propylene composites were successfully prepared by applying pressure and heating. The composite was characterized by using scanning electron microscope (SEM), and Energy-dispersive X-ray spectroscopy. The composites showed maximum electrical conductivity of 878 mS/cm. The composites showed maximum EMI SE of 120.11 dB at 9.27 GHz with the double layer thickness of 0.723 cm and possessing ~100% shielding efficiency above 0.723 cm of thickness. In addition, composite with the thickness of 2.56 mm have maximum shielding efficiency of 99.99999395% of incoming radiation. Hence, the composite can be utilized in various application areas such as automobiles, military and other electronics.
