摘要

针对隐身和电磁防护技术对轻质、高效新型吸波材料的需求，以ZIF-67为前驱体，通过1064 nm激光辐照快速制备Co/C复合粒子。研究辐照功率对Co/C复合材料物相、微结构、电磁参数及其2~18 GHz波段吸波性能的影响。结果表明，激光辐照制备的Co纳米晶尺寸可稳定在5~20 nm，复合材料展现出丰富的Co-C界面，从而利于提升材料对电磁波的介电损耗能力。特别地，45 mW激光辐照获得的Co/C工作频段可覆盖完整的X波段（厚度为2.6 mm），最低反射损耗高达-53.9 dB，展现出优异的吸波能力。

期刊介绍： Researching is owned by Chinese Laser Press (CLP), which is established by Shanghai Institute of Optics and Fine Mechanics and Chinese Optical Society in 2009. Nowadays, CLP publishes 11 journals and manages three online platforms. Journal publishing activities include both traditional and digital models, and the first journal can be traced back to 1964. The CLP Online Library includes the CLP journals and partnered ones in China, and provides literature and intelligence services for users. The product platform, named as OEShow, connects sellers and buyers of optoelectronics products. Researching (formerly known as The CLP Publishing) is featured with stable operation and leading technology, collects CLP journals and partnered optics and photonics journals, and provides readers an optical publishing platform with global influence. CLP is on the way of building a modern publishing group combining traditional business and digital publishing.
