Four novel electron-withdrawing/donating groups-graphene-oxide-oxidized-multiwalled carbon nanotubes (EWG/EDG-GO-o-MWCNTs) nanocomposites were synthesized via Aldol reaction. The EWG and EDG were successfully grafted onto GO-o-MWCNTs, which were investigated by fourier transform infrared spectroscopy (FT...
