In this study, the EMI shielding properties of Ni-CNTs/PMMA composites have been investigated. The Ni-CNTs were prepared by electroless nickel plating method. The surfaces properties of the Ni-CNTs were characterized by AAS and SEM. Electroconductivity and EMI shielding effectiveness of the composites were investigated by 4-probe multi-meter and EMI shielding tester (E5064A/EM2107A, AGILENT), respectively. As experimental results, it was found that the EMI shielding effectiveness of the composites enhanced with nickel plating time. It could be concluded that nickel content on the CNTs plays a role in determining the EMI shielding effectiveness. |
