Ultrathin two-dimensional (2D) polymers are emerging as promising alternatives for non-volatile resistive memory devices because of their high flexibility, three dimensional-stacking capability, simple structure, transparency, easy fabrication and low cost. Until now, graphene and transition metal dichalcogenide nanosheets or their composites remain the popular pick among such ultrathin 2D materials. However, the device performance including the ON/OFF current ratio, endurance, retention time and switching voltage is far from the criteria of practical data storage technology. Therefore, design and synthesis of novel ultrathin nanomaterials as active layers for high performance non-volatile resistive memory devices is urgently required. Here, we present the facile synthesis of a solution processed 2D polymer film with a large area and uniform thickness of 2 nm on a silicon substrate. The polymer has been characterized by AFM, SEM, TEM and various other spectroscopic techniques. Interestingly, the as-synthesized polymer shows typical bipolar current-voltage (I-V) characteristics of a resistive random-access memory (RRAM) material with a high ON/OFF current ratio, long retention time and high endurance. Details of this work will be presented.
