Abstract
Resistive switching effect based on graphene-embedded poly(4-vinyl phenol) composite film by spinning coating have been investigated. The nonvolatile WORM characteristics were researched. The influence of the increasing content of graphene on the resistive switching characteristics is mainly manifested in the increase of current in high resistance state, the decrease of the threshold voltage and the decrease of the ON/OFF ratio. The nonvolatile WORM characteristics of graphene poly(4-vinyl phenol) composite thin films could be ascribed to continuous conductive pathways caused by the graphene during spin-coating of the poly(4-vinyl phenol) composites on ITO substrates.
