Abstract :
A novel polymer-based multi-wall carbon nanotubes (MWCNT) with high shielding effectiveness (SE) is proposed. The MWCNT composites are tested to evaluate the electromagnetic (EM) shielding against emitted radiation from the plastic packaging. The results show that the SE of MWCNT composites exhibit 38-45 dB in far field and 28-40 dB in near field at a frequency range of 1 to 3 GHz. The MWCNT composites with their good SE are potentially suitable for use in low-cost optical transceiver modules with low electromagnetic interference (EMI)
