Graphite oxide (GO) has been selectively reduced (SGO) by H+/Na/methanol for conversion of –COOH to –OH groups. Enhanced H-bonding is confirmed between SGO and bistartratocuprate(II)4− via FTIR. The graphene/copper nanocomposite subsequently prepared by its in situ reduction showed superior EMI shielding properties compared to conventionally obtained nanocomposites.
