| Description |
The synthesis process of reduced graphene oxide (rGO) sheets generally requires the printing of graphene oxide (GO) as a
frst step and later its reduction through a chemical or thermal route to get the required rGO in the second step. The present
work demonstrates the printing of rGO using 0.1% w/v dispersion of GO in water in a single-step process. The method uses
the nascent electrochemical additive manufacturing, which allows for non-template-based deposition of microscopically
patterned systems. The samples are deposited at 1, 3, and 5 V at 0.1 mm s
ā1 printing speed. Deposited rGO is characterized
using XRD, Raman, and FTIR for various qualitative and quantitative aspects. The surface morphology and topographical
studies are performed using SEM and AFM techniques. The RMS roughness calculated using the AFM results, ranging from
5.7 nm to 15.3 nm for 1 to 5 V, indicates the trend of increasing roughness with the deposition potential. The XAS spectroscopy data show that the sample printed at 5 V has the highest purity rGO. The capacitive behaviour of the as-deposited rGO
has also been discussed and contrasted with the rGO deposited using other prevalent methods. The specifc capacitance of
the micro capacitor was found up to 10.84 F gā1 with coulombic efciencies for 500 cycles at 0.2 A gā1
