Exceptional electromagnetic shielding efficiency of silver coated carbon fiber fabrics a roll-to-roll spray coating process

We have reported exceptionally high electromagnetic interference (EMI) shielding effectiveness (SE) for flexible weaved carbon fiber fabrics (CFFs), which were spray-coated with Ag nanoparticle ink without surface modification of the CFF substrate. CFFs spray coated with Ag on a roll-to-roll (R2R) platform with a total composite thickness of 460 μm exhibited a remarkable EMI SE of 102 dB, with a density of 0.52 g cm −3 . The specific EMI SE and absolute EMI SE obtained were 194 dB cm 3 g −1 and 4266 dB cm 2 g −1 , respectively. These results suggest that the R2R spray coating of conductive metal inks such as Ag on CFFs is an economical, promising, and scalable approach for manufacturing fabrics with exceptional EMI SE. The continuous and scalable fabrication of silver coated carbon fiber fabrics with exceptional EMI shielding effectiveness via a roll-to-roll spray coating process.
