EMI shielding based on MWCNTs/polyester composites
Source abstract
Abstract
This paper presents the dielectric properties and shielding effectiveness (SE) of multi-walled carbon nanotubes and polyester (MWCNTs/PE) composite. A rectangular waveguide transmission line technique was used to measure dielectric properties, er, SE of MWCNTs (1–20 weight percentage, wt%) and PE composite in microwave frequency region from 8.2 to 18 GHz. It was observed that the increase of MWCNTs resulted in the increase of dielectric properties, loss tangent, and conductivity. MWCNTs/PE composite samples with high conductivity had led to greater SE. The results show SE of the composites increased as the amount of the MWCNTs increased. The average values of electromagnetic interference SE of the MWCNTs/PE samples with 1 wt% MWCNTs and 20 wt.% MWCNTs were 3 and 35.2 dB, respectively. Simulated and measured results of shielding effectiveness had been compared with various of MWCNTs/PE composite over the entire frequency range with a 3 mm thickness. From the results, observed that the MWCNTs/PE composite has potential use as EMI shielding materials.
