Flexible reduced graphene oxide based papers: Fabrication and properties
Tseung Yuen Tseng
National Chiao Tung University, Taiwan
Anovel way to synthesize flexible and conductive reduced graphene oxide (rGO) based papers is reported. The multi wall
carbon nanotubes (MWCNTs) are added into rGO to make rGO/MWCNTs nanocomposite papers. Their electrochemical
performance is investigated in various electrolytes, such as KOH, LiOH, and NaOH. The super capacitive behavior of the papers
is examined via cyclic voltammetry, galvanostatic charging-discharging and electrochemical impedance spectroscopy. Their
physical properties are characterized by X-ray diffractometer, Raman spectrometer, surface area analyzer, thermogravimetric
analysis and field emission scanning electron microscope. The rGO/MWCNTs paper synthesized with suitable amount of
MWCNTs exhibits excellent performance in KOH with specific capacitance of 200 Fg-1 , energy density of 22.5 Whkg-1 and
power density of 115 Wkg-1 at current density 0.25 Ag-1. Such high performance of the paper can be used for making future
supercapacitors.
