Environmentally friendly synthesis of p-doped reduced graphene oxide with high dispersion stability by using red table wine.

Reduced graphene oxide (rGO) with high dispersion stability and p-type semiconducting property was synthesized by using environmentally friendly mussel-inspired chemistry with red table wine. (+)-Catechin and tannic acid, polyphenolic model compounds present in wine, were selected and successfully utilized for the synthesis of soluble polycatechol-functionalized rGO.
