摘要

科技进步加剧了电磁干扰（EMI），因此需要更优质的屏蔽材料。本研究详细介绍了利用电纺丝技术制造由氟橡胶 (FKM) 和导电炭黑 (CB) 组成的轻质柔性纤维涂层。在 X 波段频率范围内，采用 OATS（开放区域测试点）方法对所制成的复合材料的电磁干扰屏蔽性能进行了全面评估。经验数据表明，FKM/CB 复合纤维实现了出色的屏蔽性能，平均屏蔽效果为 -69 dB，在 8.4 GHz 时的峰值为 -72 dB。该复合材料还显著降低了雷达截面（RCS），增强了其隐形能力，使其成为国防应用的主要候选材料。

Synergistic effects of carbon black and electrospun FKM fibers for superior EMI shielding

Technological advancements have exacerbated electromagnetic interference (EMI), necessitating superior shielding materials. This study details the creation of lightweight, flexible fibrous coatings composed of fluoroelastomer (FKM) integrated with conductive carbon black (CB), utilizing electrospinning. The EMI shielding performance of the resultant composite was thoroughly evaluated using the OATS (open area test site) method within the X-band frequency range. Empirical data indicate that the FKM/CB composite fibers achieved excellent shielding performance, with an average shielding effectiveness of −69 dB and a peak of −72 dB at 8.4 GHz. The composite also demonstrated significant radar cross-section (RCS) reduction, enhancing its stealth capabilities and making it a prime candidate for defense applications.
