제목 Inkjet-printed reduced graphene oxide/poly(vinyl alcohol) composite electrodes for flexible transparent organic field-effect transistors
초록 The characteristics of reduced graphene oxide(RGO)/poly(vinyl alcohol) (PVA) composites for inkjet-patterned electrodes of the organic field-effect transistors(OFETs) were studied. PVA was blended with graphite oxide to form the stable colloidal suspension for fine inkjet printing. The chemical reduction followed by thermal annealing was performed to increase the conductivity of electrodes. The inkjet-patterned RGO/PVA electrodes increased field-effect mobility of the bottom-contact pentacene FETs to 0.14 cm2/Vs, which was significantly enhanced relative to that of FETs with Au electrodes. Additionally, we successfully demonstrated all-carbon-based flexible transparent OFETs using inkjet-patterned RGO/PVA electrodes on plastic substrates.
