Abstract

In the process of finding stable, lightweight, cost-effective of Single Walled Carbon Nanotubes (SWCNTs; 1wt% & 2.5 wt%)/Polypyrrole (PPy)nanocomposite film with paraffin wax was prepared to solve the EMI problems in high frequency radiation (radio/microwave) which are useful in day-to-day applications. The nanocomposite materials were prepared by Solution mixing method and prepared the film by commercial Paraffin wax and the film thickness about 1 mm. The nanocomposite materials were characterized by structural, behavioral and morphological analysis. The composite film was further analyzed by EMI Shielding Effectiveness (SE) by microwave test bench. The resultant value was found by Voltage Standing Wave Ratio (VSWR).Moreover, Return loss (RL), Mismatch Loss (ML), Reflection Coefficient (RC), skin depth, absorption loss, reflection loss, multiple reflectionand Shielding effectiveness (SE) also calculated from the VSWR. The end result indicated that higher weight percentage (2.5 wt%) of SWCNT yielded higher SE. The discussed results showed that the prepared PPy and SWCNT based nanocomposite materials are well suited for EMI shielding applications.
