Material- and process-effects on homogeneity and electric properties of transparent conducting films composed of hydrazine-reduced graphene oxide and/or silver nanowire

•h-rGO films prepared by spin-coating are more homogeneous than those by dip-coating.•Large-sized h-rGO(NiSiNa) films prepared with a rotation number of 2000rpm had wrinkles.•Larger ratio of pyrrolic nitrogen to oxygen-bound nitrogen gave smaller WF values.•Mechanical pressing at 100°C made the thickness of AgNW films small.•The arithmetic average roughness of h-rGO/AgNW/Cytop film was 1.2nm.
