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 technology for the fabrication
of flexible SCs based on lignin-derived LIG demonstrated great potential
to use a low-cost, renewable material for the manufacture of portable
and wearable electronics.
