▎ 摘  要

Axiolitic zinc oxide/reduced graphene oxide (ZnO/r-GO) hybrid was achieved by a facile one-step hydrothermal route in this work. The axiolitic ZnO rods with uniform size were equally implanted in r-GO nanosheets. The composites exhibit prominent microwave absorption performance with the Min. RL of -55.7 dB for a thickness of merely 2.0 mm and effective absorption bandwidth covering the whole Ku band, which benefits by the introducing of axiolitic ZnO rods and constructing distinct structures. The synergistic effect of dipole polarization, interface polarization and conductivity manifestly boost the microwave attenuation capacity. The results indicated that the axiolitic ZnO/r-GO hybrid is a promising candidate for application in the field of microwave absorption, electromagnetic interference shielding, communication and safety information, etc. (C) 2019 Elsevier B.V.
