Exceptional Electromagnetic Shielding Efficiency of Silver Coated Carbon Fiber Fabrics via Roll-to-Roll Spray Coating Process
We report 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 CFFs substrate. CFFs spray coated with Ag on a roll-to-roll (R2R) platform with a total composite thickness of 460 μm exhibited remarkable EMI SE of 102 dB, with a density of 0.52 g/cm3. The specific EMI SE and absolute EMI SE obtained were 194 dB∙cm3/g and 4266 dB∙cm2/g, respectively. These results suggest that 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.
