摘要： Protective clothing plays a vital role in safety and security. Traditional protective clothing can protect human body from physical injure. It is highly desired if modern wearable electronics can be integrated into traditional protection suit to endow it with versatile smart functions. However, it is still challenging to integrate electronics into clothing through a practical approach while keeping the intrinsic flexibility and breathability of textiles. In this work, we realized the direct writing of laser-induced graphene (LIG) on Kevlar textile in air and demonstrated the applications the as-prepared Janus graphene/Kevlar textile in intelligent protective clothing. The C=O and N?C bonds in Kevlar were broken and the remaining carbon atoms were reorganized into graphene, which can be ascribed to photothermal effect induced by the laser irradiation. Proof-of-concept devices based on the prepared graphene/Kevlar textile, including flexible Zn-air batteries, electrocardiogram electrodes, and NO2 sensors, were demonstrated. Furtherly, we fabricated a self-powered and intelligent protective clothing based on the graphene/Kevlar textile. The laser induced direct writing of graphene from commercial textiles in air conditions provides a versatile and rapid route for the fabrication of textile electronics.
