Abstract

To solve electromagnetic pollution, microwave absorption materials with high performance have gained attention. Manipulating the impedance matching is an effective strategy to obtain the outstanding electromagnetic wave absorption material. In this work, a series of titanium dioxide/reduced graphene oxide (TiO₂/RGO) composites were prepared by the hydrothermal method for microwave absorption. The relationship between the microstructure and microwave absorption performance of the composite was analyzed in detail. The impedance matching and attenuation ability of TiO₂/RGO composites could be precisely manipulated by regulating the titanium dioxide content. The reflection loss and effective absorption bandwidth of the TiO₂/RGO composite could reach −46 dB and 3.36 GHz (1.9 mm), respectively. Thus, the lightweight TiO₂/RGO composite has the potential application in microwave absorption.
