SFSCs are laser-printed via the LIG method of laser pyrolysis using commercial CO2 laser CNCs to photopyrolyze polyimide precursors into porous graphitic structures (graphene-based foams) of high electrical conductivity and double-layer capacitance. The LIG method, pioneered by the James Tour team of Rice University in 2014, was further investigated in earlier works by the Romanian team and was adapted to accommodate high-resolution printing of intricate designs, such as space-filling curves.
