We present a versatile and highly substrate-independent approach for preparing multisandwich layersbased on thermally reduced Graphene Oxide (rGO) which gets strongly attached by bio-interfactantsusing a layer-by-layer (LBL) aqueous dipping and rinsing process. The process allows for the deposition ofhomogeneous ultra-thin films (∼5.5 nm) in distinct surface topographies, thicknesses and compositionsby varying the bio-interfactant layer(s). The layers formed on quartz or other semi conductive material areelectrically conductive, flexible, and transparent. The here-developed approach could be applied for thefabrication of wearables, sensors, and antistatic transparent films.
