Multifunctional MXene-decorated cotton fabric with different weaves, outstanding photothermal effect, and rapid response

The cotton fabric materials have gained widespread attention on account of their tailorable shape, flexible deformable, and lightweight in recent years. Nevertheless, there are still certain challenges in fabricating flexible, wearable, and multifunctional smart cotton fabric to satisfy versatile applications. Herein, the multifunctional smart cotton fabrics with different weave structures (plain weave, twill weave, and satin weave) were manufactured via decorating of two-dimensional (2D) carbides/nitrides (MXenes) nanosheets onto cotton fabric. The effects of cotton fabric with different weave structures on the load capacity of MXene were investigated, further exploring photothermal conversion performance and sensing performance. The MXene-decorated cotton fabrics exhibited excellent photothermal performance and mechanical double response performance. Thereinto, the MXene-decorated satin fabric (M-satin fabric) displayed ultrahigh photothermal conversion ability, its maximum equilibrium temperatures could reach 251.7 °C and 49.5 °C under 808 nm NIR laser (1.00 W cm −2 ) and 1 sun illumination (1.00 KW m −2 ), respectively. Moreover, the MXene-decorated satin fabric sensors also exhibited excellent responsiveness and rapid response time of ∼0.7 s. Thus, multifunctional MXene-based cotton fabrics have great promise in intelligent garments, wearable heater, and wearable electronics.
