Porous Co9S8 Nanotubes with Percolation Effect for Lightweight and Highly Efficient Electromagnetic Wave Absorption

Abstract

Developing lightweight and thin electromagnetic (EM) wave absorbers with broad bandwidth remains a major challenge for reducing the EM pollution originated from the rapidly expanding electronics. Herein, porous Co9S8 nanotubes synthesized through a facile self-template method are applied as a single-component EM wave absorber. Based on percolation theory, an appropriate balance between excellent impedance matching and strong loss ability can be achieved for the Co9S8/paraffin composite with 30 wt% filler loading, giving rise to a broad effective absorption bandwidth almost covering the entire Ku band, or X band with varied Co9S8 loading. This study provides new concept on the design of single-component EM wave absorbing materials with even superior performance to that of many multicomponent absorbers.
