Interfacial polarizations induced by incorporating traditional perovskites into reduced graphene oxide (RGO) for strong microwave response
Incorporation of traditional perovskites into reduced graphene oxide (RGO) is an effective strategy to develop useful microwave absorbents. Taking advantage of the suitable impedance of La0.7Sr0.3MnO3 (LSMO), a novel and available microwave absorber was obtained. Here, we showed an outstanding and stable RGO material decorated with LSMO that can be used as an active component of microwave absorption devices. The as-prepared LSMO/RGO composites adopted the merits of RGO and LSMO and provided good properties, such as a controllable dissipation ability, optimized impedance matching, and broadened effective frequency bandwidth. For example, the minimum reflection loss (RL) value of LSMO/RGO composites with a 60% loading filler ratio reached -38.81 dB with a matching thickness of only 1.7 mm. Furthermore, the effective frequency bandwidth can be as wide as 5.64 GHz, with a thickness of 1.95 mm. Therefore, this work initiates a brand new avenue for artificial research of new materials for electromagnetic wave absorption.
