In this paper, Co-doped ZnO nanoparticle and nanofiber are prepared by electrospinning method. The results show that Co-doped ZnO nanofiber performs bead-like fibrous shape and exhibits ferromagnetic properties. The dielectric loss and magnetic loss properties of Co-doped ZnO nanofiber are much better than those of Co-doped ZnO nanoparticle due to the improvement of dipole polarization, interfacial polarization and shape anisotropy. The absorptivity of Co-doped ZnO nanofiber can reach 70% in the frequency range of 5.3-18 GHz when the coating thickness is 1.5-4.0 mm. It is demonstrated that the bead-like fibrous shape is beneficial to optimize electromagnetic loss and microwave absorption properties of Co-doped ZnO. (C) 2018 Elsevier B.V. All rights reserved.
