A Water contact angle average values of the indicated PAN/G membranes. B, C Plots of the relative dielectric permittivity (B) and electric conductivity (C) at different values of applied frequency of the PAN/G2; PAN/G10 and PAN/G15 membranes measured by means of electrical impedance. D Comparison of the Raman spectra of graphene (red), PAN/G0 (blue) and PAN/G10 membranes (black). EH Surface mapping (0.144 × 0.088 mm) of PAN/G10 membrane showing the intensity of band G of graphene (IG, E), intensity ratio of D and G bands of graphene (ID/G, F) intensity ratio of 2D and G bands graphene (I2D/G, G) and intensity ratio of nitrile (CN) characteristic band of PAN polymer and G band of graphene (ICN/G, H)
