A kind of pollution known as electromagnetic interference (EMI), which results from ubiquitous usage of various electronic communication and military radar equipment, has been receiving increasing attention recently. However, large-area EMI shielding on transparent and/or curved surfaces, including building windows, curved glass wall, and special requirements spaces (SRSs), remains hard to achieve. In this paper, a silver nanofiber (AgNF) based flexible and transparent EMI shielding film was successfully assembled via a room-temperature roll-to-roll production method. For transparent application scenario, AgNF with 89% transmittance in visible range and 1 μm thickness shows ~20 dB shielding efficiency (EMI SE). On the other hand, total shielding (>50 dB) is obtained when the thickness of AgNF increases to 10 μm, while its transmittance in visible range remains higher than 75%. Considering the facile and scale-free production technology, this material can be readily applied in large-scale, transparent, and/or SRSs EMI shielding.

近来，由于各种电子通信和军用雷达设备的普遍使用而导致的一种称为电磁干扰（EMI）的污染受到了越来越多的关注。但是，仍然难以实现透明和/或弯曲表面（包括建筑物窗户，弯曲的玻璃墙和特殊要求空间（SRS））上的大面积EMI屏蔽。本文通过室温卷对卷生产方法成功组装了基于银纳米纤维（AgNF）的柔性透明EMI屏蔽膜。对于透明的应用场景，AgNF在可见光范围内的透射率为89％，厚度为1μm，具有约20 dB的屏蔽效率（EMI SE）。另一方面，当AgNF的厚度增加到10μm时，可获得总屏蔽（> 50 dB），而在可见光范围内的透射率仍高于75％。考虑到简便，无规模的生产技术，该材料可轻松应用于大规模，透明和/或SRS的EMI屏蔽。
