Herein, we are reporting a rapid one-pot synthesis of MoS2-decorated laser-induced graphene (MoS2-LIG) by direct writing polyimide foils. By covering the polymer surface with layer MoS2 dispersion before processing, it is possible to obtain an in situ decoration porous network during laser writing. The resulting material three-dimensional arrangement agglomerated and wrinkled flakes decorated nanosheets good electrical properties high area, suitable be employed as electrodes for supercapacitors, enabling both electric double-layer pseudo-capacitance behaviors. A deep investigation has been performed understand chemical physical characteristics hybrid MoS2-graphene-like material. Symmetric supercapacitors have assembled planar configuration exploiting polymeric electrolyte; performances here-proposed allow prediction enormous potentialities these flexible energy-storage devices industrial-scale production.
