摘要

织物基电磁干扰屏蔽材料具有良好的柔韧性和较高的电磁干扰屏蔽效能。然而,基于纺织品的电磁干扰屏蔽材料的机械性能差限制了它们的应用。碳丝(CF)结合了优异的机械性能和导电性。因此,我们展示了cf增强材料,该材料与两种类型的铜涂层非织造聚酯(CuPET10和CuPET20)层压,用于电磁干扰屏蔽。与传统的层压工艺相比,采用粘衬熨烫工艺更为方便。所开发的层叠板(CuPET/CF)具有优异的EMI屏蔽性能,在30 MHz至3 GHz频率范围内平均SE值为88.6 dB。CuPET10/CF和CuPET20/CF的力学性能分别从12.7 MPa提高到39.9 MPa和13.46 MPa提高到35.78 MPa。新开发的材料还表现出优异的轻质、柔韧性和耐热性。层压CuPET/CF材料提供增强的机械性能和易于层压的能力,使其能够屏蔽电磁辐射敏感设备的表面,同时提供一定程度的保护和极高的EMI屏蔽效率。

Enhanced electromagnetic shielding of lightweight copper-coated nonwoven laminate with carbon filament reinforcement
Textile-based electromagnetic interference (EMI) shielding materials with good flexibility and high EMI shielding effectiveness (SE) are highly desirable. Still, the poor mechanical properties of textile-based EMI shielding materials limit their application. The carbon filaments (CF) combine superior mechanical properties and conductivity. Therefore, we demonstrate the CF-reinforced material, which was laminated with two types of copper-coated nonwoven polyester (CuPET10 and CuPET20) for EMI shielding. Compared to the traditional lamination method, this process was more convenient by ironing with adhesive lining. The developed laminate (CuPET/CF) performs superior EMI shielding property with an average SE value of 88.6 dB in the frequency range of 30 MHz to 3 GHz. The mechanical properties were improved from 12.7 to 39.9 MPa and from 13.46 MPa to 35.78 MPa for CuPET10/CF and CuPET20/CF, respectively. The newly developed material also demonstrated exceptional lightweight, flexibility, and thermal resistance. The laminated CuPET/CF material provides enhanced mechanical properties and easy lamination capability, allowing it to shield surfaces of electromagnetic radiation-sensitive equipment while providing a certain degree of protection and extremely high EMI shielding efficiency.
