Laser-Induced Graphene Derived from Kraft Lignin for Flexible Supercapacitors.

ABSTRACT: Porous graphene was photothermally induced from kraft lignin via direct laser writing. This laser-induced graphene (LIG) possessed a hierarchical structure with a three-dimensional (3D) interconnected network ideal for its transfer from the kraft lignin/poly(ethylene oxide) (KL/PEO) film onto polydimethylsiloxane (PDMS). The resultant LIG/PDMS composite was shown to keep the intrinsic porous structure and electrically active sites of LIG. The supercapacitors (SCs) fabricated using the LIG/PDMS composite exhibited good electrochemical performance and excellent cyclic stability. More than 90% capacitance was retained after 10 000 cycles. Moreover, due to their high flexibility, the SCs were able to endure bending deformation without significantly sacrificing their capacitance. The proposed t
