GO tab assembly and characterization. (a) Image of the GO membrane and the cellulose filter after vacuum filtration. (b) Free-standing membrane removed from filter after drying and a GO tab after fabrication. (c and d) Assembly of GO tab. The GO membrane is adhered to double-sided PSA with a 1-mm through-hole cut out. (e) Microscope image of the GO tab edge showing uniform distribution of flakes and the acceptably clean cut from the knife cutter. (f) SEM image of the GO membrane showing a multilayer stacked structure.
