Title: | Unique electromagnetic loss properties of Co-doped ZnO Nanofiber | Authors: | Huang, X Or, SW |
Issue Date: | 1-Mar-2019 | Source: | Materials letters, 1 Mar. 2019, v. 238, p. 271-274 | Abstract: | 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. | Keywords: | Electromagnetic loss Electronic materials Magnetic materials Zinc oxide |
