Self-reduction assisted MXene/silver composite Tencel cellulose-based fabric with electrothermal conversion and NIR photothermal actuation

Smart e-textiles, which are capable of wireless transmission, signal conversion and energy transduction, have the capability to provide added values be more versatile. However, there still many challenges in fabricating a flexible durable smart fabric with high-level multifunctional integration. Herein, novel two-dimensional (2D) material, Ti3C2Tx MXene, zero-dimensional (0D) silver nanoparticles (AgNPs) were coupled fabricate Tencel electrical light versatility. Through self-reduction reaction, nitrate can reduced AgNPs because existence reductant, 0D an average diameter about 500 nm uniformly distributed on 2D MXene nanosheets, enabling conductive points paths for MS fabric. Benefiting from excellent hydrophilicity rich terminals interface bonding force was enough get uniform Because enhanced conductivity MXene/AgNPs, MXene/silver (MS) exhibited electrothermal property (The cyclic temperature is 57.1 °C at 30 s heating time under 6.0 V voltage) as well thermal sensing performance, serve element array devices. In addition, also has photothermal (maximal bending angle 149° 31 s) due near-infrared (NIR) by asymmetric expansion two encapsulated Ecoflex layers, rapid-responsive actuator. With NIR sensitive capabilities, performed sensation potential robots.
