a XPS C 1s spectra of the 6000 cycles graphene ink. b A plot of Rs as a function of the graphene and graphite film thickness for the 6000 cycles graphene ink with different post-processing conditions such as centrifugation and annealing. Error is calculated by standard deviation of mean (SDOM, n = 3). c A graph of the σ as a function of thickness for the 6000 cycles graphene ink with post-processing. d Thermogravimetric analysis is used to find thermograms of the graphene powder and SDC surfactant. The weight change is plotted as a function of temperature.
