Abstract: In this paper we present a novel approach to prepare flexible and transparent conducting films,
whose components can be separated and recovered via a recycling process. The fabrication method
is based on low power sputtering of ultrathin gold layers on sodium alginate free-standing films.
The resulting foils are thin, easy to handle and shape, while showing good conductive properties. In
particular, they show excellent resistance to mechanical stress, like bending or rubbing, and are
highly stable in ambient atmosphere over several months. Therefore they may represent a very
promising candidate to be employed in green electronics, thanks to the reduced energy consumption
required for their fabrication, the absence of toxic components or derived from oil, and the
possibility to disassemble the devices at the end of their life in environmentally friendly conditions.
