The construction of an organic-electronic resistive switch based on polymer electrolytes is the basis to study the
interfacial and bulk transport as well as the interaction between ions and electrons/holes at the nanoscale level.
Moreover, it could also be potentially applied in novel nanoelectrochemical devices for sensors, fuel cells and batteries,
and therefore has attracted much attention in recent years. In this work, we fabricated resistive switching devices with
silver-ion-conductive polymer electrolytes. The devices showed bipolar switching behaviors in the current-voltage
characteristics for different silver ion concentrations ranging from 1 to 4 wt%. A high resistance up to 1 GΩ in the OFF
state and a low resistance with less than tens of kΩ in the ON state can be achieved. We believe that the observed
switching results from formation and annihilation of Ag metal filaments inside the polymer film by solid electrochemical
reaction. Sequential operations, such as write-read-erase-read, were also demonstrated.
