▎ 摘　　要

The development of wearable electronics has facilitated the growth of flexible energy storage systems, including micro-supercapacitors (MSCs). Thus, it is urgent to fabricate MSCs with both excellent mechan-ical strength and electrochemical performance. In this work, P-enriched laser-induced graphene (LIG) is fabricated for the first time on Kevlar textiles via the one-step laser direct writing process. Laser engrav-ing is employed on polyvinyl alcohol (PVA)/H3PO4-coated Kevlar to obtain porous graphene and simulta-neously in-situ dope phosphorus in pure LIG. The unreacted gel dopant could be removed by washing in hot water because of the thermal solubility of PVA, therefore the Janus LIG/Kevlar textiles keep well flexible and skin-friendly. Moreover, the phosphorus-doped LIG has optimized porous morphology compared to pure LIG, which benefits the interface between electrolyte and electrodes. The introduction of phos-phorus contributes to the electrochemical performance attributed to the optimized porous morphology and pseudocapacitance brought by phosphorus doping. The obtained in-plane MSCs (PMSC-4) on Kevlar textiles present a high areal capacitance of 125.35 mF cm(-2), good cycling stability (over 88% during 10,000 cycles), and flexibility. This work provides a facial and scalable method firstly to fabricate and optimize heteroatom-doping MSCs on Kevlar, showing potential for wearable electronics and electronic textiles.
