Resumo(s): | The development of polymer-based conductive inks has gained increasing interest in the areas of printed and molded electronics. Graphene-based materials are explored in this scope, reduced graphene oxide (rGO) being among the most used conductive filler components of the inks. Herein, rGO is doped with nitrogen to obtain N-rGO; the replacement of oxygen atoms by nitrogen ones increases the electrical conductivity of graphene. Polymer-based conductive inks reinforced with graphene are developed based on polyvinylpyrrolidone (PVP) as polymer binder and dihydrolevoglucosenone (Cyrene) as solvent, leading thus to environmentally friendly conductive inks. Screen-printable inks are optimized in terms of viscosity and adhesion properties, leading to printed films with sheet resistance close to Rs=1ksq1, the graphene:PVP inks being also biocompatible and nontoxic. |
