“…In addition, similar to carbon materials, activated biochar (AC) has full-spectrum sunlight absorption properties and excellent photothermal conversion performance and has received considerable attention in various photoinduced applications such as solar-thermal evaporators, photocatalysts, and so forth. On the other hand, copper sulfide (CuS) has the double advantages of conductivity and strong absorption of near-infrared light and has been widely used in the fields of electromagnetic interference shielding (EMI) and electrothermal wearable devices. − For instance, Yu et al prepared a wearable thermal management fabric by in situ growth of CuS nanoparticles on the surface of cotton fabric, which exhibited a 46 dB EMI value and higher photothermal (87 °C, 0.1 W/cm 2 OPD) and electrothermal (88 °C, 3.5 (v)) conversion performance.…”
