摘要：

Broadening absorption bandwidth is of great significance to extend application scenarios for electromagnetic wave (EMW) absorption materials. Since the electromagnetic character changes caused by high shape anisotropy, one-dimensional fibrous materials have been widely concerned. In this work, manganese sulfide (MnS)/carbon nanocomposite fibers are facilely synthesized by a facile combination of electrospinning and high-temperature processing. The fibrous carbon supports with a 350-nm average diameter are embedded with dense MnS nanoparticles on the surface. Under the premise of ensuring a strong EMW absorption intensity (-68.9 dB, 11.1 GHz, 3.6 mm), the MnS/carbon nanocomposite fibers can achieve a wide effective absorption bandwidth of 7.2 GHz (9.5-16.7 GHz, 3.3 mm). In-depth study verifies that MnS can help to achieve superior synergy between conductive and polarized attenuation capacity, enhance the attenuation ability and optimize impedance matching characteristic. Besides, considering the few studies about MnS in this field, this work confirmed the huge potentials of MnS for EMW absorption applications. (c) 2022 Published by Elsevier Ltd.
