چکیده مقاله:
In the present work,MoS2 decorated graphene nanocomposite powders were synthesized by laser scribing method.Theobtainedflexible light-scribed graphene/MoS2composites are very suitableas micro-supercapacitors and thus their performance was evaluated at different concentrations.The effect of laser scribing process to reducegraphene oxide (GO) was investigated. The GO/MoS2composite wassynthesized using a chemical mixing of GO solution withMoS2/Dimethylformamide (DMF)solution.Themixtures with various concentrations of MoS2were then coated on a LightScribe DVD disk and laser scribed to reduce GO and create aMoS2/laser-scribed graphene (LSG) composite. Four different concentrations of MoS2/LSG composites (pristine rGO, 1:100, 1:75 and 1:50 MoS2/LSG) were utilized as supercapacitor electrode and the electrode with the best performance was selected for flexible micro-supercapacitor applications. The present findingsdemonstrate that MoS2/LSGmicro-supercapacitor has high specific capacitance per area. The sample with MoS2/LSGvolume ratio of 1:50 shows the highest specific capacitance (~ 8 Fcm-3) and itscyclic stabilityis favorable over 1000 cycles. Keywords:Graphene oxide, laser scribed graphene,MoS2/LSG nanocomposite, micro-supercapacitor, RGO, Microstructure, DVD.
