Abstract
Sodium copper chlorophyllin (SCC)- polyvinyl alcohol (PVA) composites thin films have been prepared on flexible and transparent ITO/PET substrates using Ag as the top electrode. FE-SEM shows that the prepared SCC-PVA thin films are smooth and dense, SCC particles have embedded in PVA and formed nano-islands, which are distributed irregularly in the thin film. The optical transmittance spectrum demonstrates that Ag/SCC-PVA/ITO/PET can be used as a transparent electronic device. I–V characteristics of the Ag/SCC-PVA/ITO/PET show that the device exhibits self-rectifying resistive switching performance, which could be related to the forming/rapture of Ag conductive filaments induced by the migration of Ag ions. This study demonstrates the potential uses of SCC-PVA in low-cost, flexible and transparent resistive switching memory.
