Synthesis and Characterization of Graphene and Molybdenum Disulfide based multilayered 2D Nanomaterials for EMI Shielding Analysis

Abstract

It is still very challenging to effectively design the nanocomposites microstructures which significantly improve their electromagnetic interference shielding effectiveness (EMI SE). Herein, we developed a facile method for fabrication of graphene nano platelets/Molybdenum disulfide GNPs/MoS2 nanocomposites, in which GNPs are utilized as highly effective electrical transport materials while MoS2 resolves the agglomeration problem of GNPs along with serves as an efficient cluster of electrical transport systems and dampens the incoming electromagnetic wave. There are two types of samples are synthesized and compared in context of EMI SE values. Physically mixed composites and layered. The sandwiched MoS2 with GNPs layered film shows an EMI SE of 24.4 dB which is almost 14% improvement relative to GNPs/MoS2 nanocomposites containing 0.5 wt.% GNPs exhibit an EMI SE value of 21.01dB. This work provides a new strategy for the design of multi-functional nanocomposites for EMI shielding for future applications.
