Organophosphorus-based Polymer Covalently Functionalized Reduced Graphene Oxide: In-situ Synthesis and Nonvolatile Memory Effect

The best strategy to improve the solubility of two-dimensional materials is merge them into a polymer backbone or a polymer matrix to form new kind of functional materials. A novel ?-conjugated and highly soluble organophosphorus-based polymer covalently functionalized reduced graphene oxide derivative material, PTPEB-g-RGO, has been successfully synthesized, characterized, and was used as active layer material in resistive random access memory (RRAM) devices. The as-fabricated Al/PTPEB-g-RGO/ITO device exhibited nonvolatile bistable resistive switching performances with a large ON/OFF current ratio surpassing 104, long retention time over 104 seconds, excellent endurance over 200 switching cycles, significant slight |?ON-OFF| value and remarkable repeated “write-read-erase-read-rewrite” capability. A slight value difference between the turn on voltage and turn off voltage is beneficial for reducing power consumption and decreasing information misreading rate in digital memory cell. The present research work offers a significant insight for the future development of organic memory devices by taking advantage of organophosphorus-based polymer material.
