Electronic pollution, such as electronic noise, electromagnetic interference (EMI), and radiofrequency interference (RFI), has increased as a result of the rapid growth and heavy use of electronic gadgets, causing electronic device problems. Because of their unique qualities, such as electrical, thermal, mechanical, and magnetic properties, flexible polymer composites have a great potential for electromagnetic shielding. Because of their small weight and great corrosion resistance, graphene (G) and its composites can be used as better shielding materials against these interferences. To minimize radioactive pollution from electronic gadgets, researchers are currently wrestling with the requirement for flexible and scalable smart composite materials. Our current research focuses on the use of next-generation graphene (G) conductive fillers that are filled with polyvinyl chloride (PVC)/graphene (G). The composite has an extremely low percolation threshold and a high shielding efficiency (SE) against electromagnetic interference due to the absorption-dominated shielding process (EMI). SEM electron micrographs were used to confirm the distribution and dispersion patterns of graphene particles in the matrix phase. The composite, which is only 2 mm thick and includes only 40% graphene by weight, has an EMI SE value of 26 dB in the frequency range of 10 to 15 GHz. We feel that the best solution, in this case, is to promote a scalable and industrially viable G/PVC composite, which is a novel and strong candidate in the expanding field of high-stress electromagnetic shielding applications in the future.
