Multifunctional Polyimides for Resistive Switching Memory Devices Based
on Flexible Transparent Polyimide--AgNWs Hybrid Electrodes
Abstract
With the quick development of flexible memory electronics,
multifunctional organic materials have been the necessary for fabricate
electronics. In this work, the highly transparent and flexible electrode
was successfully prepared by coating the high-performance silver
nanowires (AgNWs) onto the colorless polyimide (PI) substrate. The
prepared flexible PI-AgNWs electrodes exhibited a low sheet resistance
of 15 Ω/sq with the high transparency of 68 % at the wavelength of 400
nm. A novel kind of polyimide TPC6FPI was successfully synthesized and
characterized with excellent thermal stabilities and high glass
transition temperature (Tg) above 250 °C. Furthermore, a
kind of flexible transparent PI-AgNWs/ TPC6FPI/Al resistive memory
device was prepared and exhibited excellent SRAM switching behavior with
the threshold voltage of around 2.1V and the ON/OFF current ratio of
~10-4, which indicated that
multifunctional PI-based memory device showed the potential to the
wearable devices.
