Figure 1. From GO sheets and cihtosan to GO/chitosan composite and the characterization of the composite electrolyte film.

Figure 1

(a) Chemical structures of GO sheet and chitosan, respectively. (b) GO sheets and chitosan were mixed in water solution and stored in a bottle (Taken by P.F.). (c) Typical Nyquist plot of the GO/chitosan composite film (black dots). For comparison, Nyquist plot of pure chitosan film is shown (red dots). (d) Cross-sectional SEM image of the GO/chitosan composite electrolyte film. The scale bar is 5 μm. (e) Specific capacitance of GO/chitosan composite electrolyte film plotted against the frequency. The inset illustrates the sandwich structure used for the capacitance and leakage current measurements (Drawn by C.W.). (f) Leakage current of the GO/chitosan composite electrolyte film.
