协同性的介电损耗和磁损耗使少层WS 2 纳米片与NiO纳米粒子的杂化物具有优异的微波吸收性能（英文）
发布时间：2021-10-25 11:29
由于高的比表面、层状结构以及特殊的电子结构,二硫化钨在电磁波吸收领域受到了科研人员的广泛关注.然而,二硫化钨有限的电磁吸收能力和带宽还有待进一步的改进,以满足其作为电磁吸收材料的实际应用.本研究采用水热法制备了具有异质结构的WS2/NiO杂化材料,并将其发展成为电磁波吸收基体.在4.27 mm厚度下,掺20%NiO杂化物材料的最大反射损失可达-53.31 dB;RL值小于-10 dB的带宽范围为4.54～18 GHz,此时吸波材料的厚度在3.5～5.5 mm.研究结果表明,WS2/NiO杂化材料优异的吸波性能是由于磁性Ni O的加入,形成了WS2和Ni O的异质界面,从而引起杂化材料协同的磁损耗和介电损耗,这为设计优异的吸波材料以及实际的应用开辟了新的途径.
