▎ 摘  要

This work reports the formulation of vinyl ether containing functionalized graphene sheets in order to produce UV-curable conductive inks. The best graphene-surfactant ratio was found to give a stable dispersion of graphene into triethyleneglycol divinyl ether (DVE3) resin, avoiding the presence of large filler aggregates that could clog printing head during ink-jet process. Propylene carbonate was used as solvent to adjust the viscosity of the formulation. The presence of graphene did not significantly hindered the UV-curing process. Cross linked nanocomposite materials show a decrease of resistivity of seven order of magnitude with respect to the pristine polymeric matrix.
