摘要	Multi-polarization structural design was proved to be a resultful strategy to achieve superior microwave absorbers but limited by the low dielectric properties. In this work, silicate-glasses (SG) nanoparticles doped with different modifier cations (M) have been synthesized by the sol-gel method. Modified silicate-glasses (M-SG) nanoparticles were loaded on reduce graphene oxide (rGO) nanosheets through hydrothermal possess and high-temperature calcination with adding a silane coupling agent (KH-550). The dielectric loss and impedance matching were improved through the synergistic effect of rGO and M-SG. The microwave absorption (MA) performance of M-SG@rGO has been highly boosted, and the minimum reflection loss (RL) is −69.2 dB with a thickness of 2.8 mm. Meanwhile, the X-band and Ku-band absorption can also be obtained with specific M-SG loading at a particular thickness. The results demonstrate that the effects of dipole polarization and interface polarization all play a vital role in improving the microwave absorption performance of M-SG@rGO absorbers. © 2021 Elsevier Inc.
