Polyaniline-copper oxide composite: A high performance shield against electromagnetic pollution

This work reports the electromagnetic interference (EMI) shielding properties of polyaniline-copper oxide PAni/CuO composites prepared by in-situ emulsion polymerization. The shielding measurements have been carried out in the microwave frequency range of 8 to 12 GHz (X-band). The composites showed...

Description
Summary:This work reports the electromagnetic interference (EMI) shielding properties of polyaniline-copper oxide PAni/CuO composites prepared by in-situ emulsion polymerization. The shielding measurements have been carried out in the microwave frequency range of 8 to 12 GHz (X-band). The composites showed total EMI shielding effectiveness (SE) of −32 to −37.3 dB (> 99.99 % attenuation) with higher dielectric loss (ε″) in the range of 142 to 165, indicating their potential as high performance shield throughout the X-band. The results indicate that the electromagnetic properties of the composites depend on the content of CuO in PAni matrix.
