Mechanisms of polarization switching in graphene oxides and poly(vinylidene fluoride) - graphene oxide films

摘要

Polarization switching in graphene oxides (GOs) and poly(vinylidene fluoride) (PVDF)–GO nanocomposite is investigated by piezoelectric force microscopy (PFM). The dynamical switching results reveal that GO films exhibit ferroelectric and piezoelectric properties with two-dimensional characteristics. Abnormal polarization switching is observed in PVDF–GO films, which is promising for electronic applications.
