The design and fabrication of a multilayered graded GNP/Ni/PMMA nanocomposite for enhanced EMI shielding behavior.

ABSTRACT: A multilayered graded structure can maximize the electromagnetic interference (EMI) shielding properties of a nanocomposite for a specific amount of a conductive filler in a polymer matrix. In this study, multilayered graded nanocomposites of graphene nanoplatelet (GNP)/Ni/polymethyl methacrylate (PMMA) were developed to achieve enhanced EMI shielding behavior. Both multilayered and monolayered nanocomposites were fabricated by controlling the compositions of GNP/Ni in the PMMA matrix. The contributions of the multilayered nanocomposite to EMI shielding were investigated and compared with the shielding effectiveness of the monolayered nanocomposite. The multilayered nanocomposite shows enhanced shielding effectiveness of around 61 dB in the X-band, which is more than three orders of magnit
