We have demonstrated that 2D insulating and hydrophilic GO nanosheet can be used as a novel adhesive OCL on the hydrophilic AgNW/PET. With GO OCL nanosheets and longer exposed plasma treatment, the maximum and mean sheet resistances decreased and the uniformity of the film increased, resulting in high quality AgNW film with a low haze. In conclusion, with ultra-thin GO nanosheet as the OCL, all of the important hurdles for the real commercialization, including high haze, low transparency, high Rsh values and mechanical instability, were simultaneously overcome, thereby producing the large area, flexible, highly transparent conductive GO/AgNW/PET film. All of the components in this system were produced using inexpensive solution processes. These wet-processable, extremely stable, mechanically compliant and physically robust TCF can be applied to large-area, flexible displays and solar cells, optical/electronic biosensors, energy nanogenerators, and transparent energy storages as a charge collectors.
