SYNERGISTIC EFFECT OF CO‐SUPPORTIVE OPEFB-MWCNT CONDUCTIVE NETWORK FOR HIGH‐PERFORMANCE EMI SHIELDING APPLICATION

Abstract

The crystallinity, microstructure, complex permittivity, and electromagnetic interference (EMI) shielding effectiveness (SE) of polymeric material filled with nanofiller were investigated. The nanofiller was multiwalled carbon nanotubes (MWCNTs). In addition, the EMI SE mechanism and dielectric properties in the X-band frequency were studied. The nanocomposites were fabricated by the melt-blending method. The effect of 5-13 wt.% MWCNTs filler on the dielectric of OPEFB/PLA/MWCNTs composites was studied. It was found that 13 wt.% MWCNTs exhibited the highest EMI SE value compared to 5, 7, 9, and 11 wt.% MWCNTs.
