Lightweight PPy aerogel adopted with Co and SiO2 nanoparticles for enhanced electromagnetic wave absorption

doi:10.1016/j.jmst.2021.04.055

Abstract

Abstract:

Lightweight nanocomposites consisting of magnetic and dielectric units aroused intensive interest as potential high performance electromagnetic wave absorbing materials. In this work, we report a facile and efficient method to fabricate (Co, SiO₂)/PPy composites with tunable electromagnetic properties. The absorbing properties and effective absorbing bandwidth can be regulated by controlling the content of SiO₂ in composites. The composite shows a maximum reflection loss (RL) of -65.31 dB at 11.12 GHz with a thickness of 3.002 mm when SiO₂ being 22 wt.%. The effective absorbing bandwidth reaches up to 5.1 GHz (8.91-14.01 GHz), which covers the entire X band (8-12 GHz). The improved impedance matching, high interfacial polarization and complex electromagnetic synergy in the composites are the key factors giving rise to the higher efficient absorption. The PPy aerogel-based nanocomposites with controllable absorption performance, lower density and strong environmental adaptability will become attractive candidates as advanced microwave absorbing materials.

Key words: Lightweight nanocomposites, PPy aerogel, Electromagnetic wave absorbing, Impedance matching, Electromagnetic synergy
