A study on EMI shielding effectiveness of graphene based structures

Following the rapid development of technology, various electrical and electronic devices have been a great part of life day by day due to make human life easier and comfortable. However, they emit electromagnetic radiations causing the electromagnetic pollution. Depending on this role, electromagnetic pollution becomes a crucial problem for humanity, environment, and negatively effected the performance of electronic devices because of the electromagnetic interference. In order to prevent the unwanted signals, we have produced a graphene based polymer composites (light weight, strong, flexible), graphene/wood-plastic (G/WP), as a shielding material and investigated its electromagnetic interference shielding effectiveness (EMI SE). Four combination of G/WP is observed with different (% 0, % 3, % 6, % 9 wt) graphene rates in 8-9 GHz frequency range. As a result, the shielding success has been attributed to the graphene increase in composite. The results claim that G/WP composites can efficiently take place in electronics technology and electronic protection.
