Multifunctional wearable electronic textile based on fabric modified by MXene/Ag NWs for pressure sensing, EMI and personal thermal management

Flexible wearable electronics with multi-functions are bound to become the future development trend in the fields of intelligent device application, involving human healthcare, dynamic thermal management and even radiation protection. Herein, we promote a facile method that combines solution immersion and suspension spraying to assemble a poly(dimethylsiloxane)/Ag NWs/MXene/fabric (PAM@fabric) device. In particular, we use poly (diallyl dimethyl ammonium chloride) (PDAC) to pretreat the cotton fabric, which enables MXene to realize electrostatic self-assembly and greatly improve its stability. The multifunctional textile-based device with three-dimensional conductive network structure of MXene and Ag NWs presents durable and sensitive pressure sensing performance for detecting human joint motions and even subtle pulse. Besides, due to the excellent electrical conductivity of MXene and Ag NWs, the electronic also exhibits outstanding electromagnetic interference (EMI) shielding, as well as electrothermal conversion performance with controllability and extended cyclic stability. Accordingly, rational design provides a feasible path to prepare flexible multifunctional wearable devices.
