Multifunctional Asymmetric Bilayer Aerogels for Highly Efficient Electromagnetic Interference Shielding with Ultrahigh Electromagnetic Wave Absorption.

When the thickness of the MG layer increases from 4 to 8 layers, the absorption coefficient of the MG-MXene aerogel shows an increasing trend (Fig. 3 d) while SE R reduces from 2.2 dB of MG 4L-MXene, to 1.1 dB of MG 6L-MXene and 0.2 dB of MG 8L-MXene (Fig. 3 e).
