Abstract
Although electromagnetic interference (EMI) shielding fabrics integrated with absorption and reflection have recently shown attractive defense performance, effective sweat management is still scarce for simultaneously achieving sustainable personal comfort. Here, we demonstrate a hierarchically arrayed fabric for personal EMI shielding and thermal comfort management. By integrating EMI shielding interfaces and spatially distributed channels, the fabric exhibits high-efficiency EMI shielding ability and enhanced sweat transportation. We demonstrate the tuning electromagnetic response with maximum EMI shielding efficiency value of ∼118 dB and continuous one-way liquid sweat flow with a temperature of ∼3.5 °C lower than that of conventional EMI shielding fabrics. In addition, the fabric shows substantially stabilized EMI shielding performance for long-term use by transporting and repelling internal liquid sweat. The high performance of our fabric makes it a promising design paradigm for personal electromagnetic interference shielding and thermal management.
