	1	Lightweight PPy aerogel adopted with Co and SiO_(2) nanoparticles for enhanced electromagnetic wave absorption显示文摘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,SiO_(2))/PPy composites with tunable electromagnetic properties.The absorbing properties and effective absorbing bandwidth can be regulated by controlling the content of SiO_(2) in composites.The composite shows a maximum reflection loss(RL)of-65.31 d B at 11.12 GHz with a thickness of 3.002 mm when SiO_(2) 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.
