Abstract

Graphene oxide-cysteamine-silver nanoparticle (GCA)/silver nanowire (AgNW)/GCA/colorless poly(amide-imide) (cPAI) structures based on cPAI substrates with polyimide and polyamide syntheses were fabricated to study their characteristics. A layer of electrodes was constructed using a sandwich structure-such as GCA/AgNW/GCA-with cPAI used as a substrate to increase the heat resistance and improve their mechanical properties. Furthermore, to overcome the disadvantages of AgNWs-such as their high surface roughness and weak adhesion between the substrate and electrode layers-electrodes with embedded structures were fabricated using a peel-off process. Through bending, tapping, and durability tests, it was confirmed that these multilayer electrodes exhibited better mechanical durability than conventional AgNW electrodes. Resistive random-access memory based on GCA/AgNW/GCA/cPAI electrodes was fabricated, and its applicability to nonvolatile memory was confirmed. The memory device had an ON/OFF current ratio of ~10@0.5 V, exhibiting write-once-read-many time characteristics, maintaining these memory characteristics for up to 300 sweep cycles. These findings suggest that GCA/AgNW/GCA/cPAI electrodes could be used as flexible and transparent electrodes for next-generation flexible nonvolatile memories.

摘要

基于具有聚酰亚胺和聚酰胺合成的无色聚（酰胺 - 酰亚胺）（cPAI）基板，制备了氧化石墨烯 - 半胱胺 - 银纳米颗粒（GCA）/银纳米线（AgNW）/GCA/无色聚（酰胺 - 酰亚胺）（cPAI）结构，以研究其特性。使用三明治结构（如GCA/AgNW/GCA）构建一层电极，以cPAI作为基板，以提高耐热性并改善其机械性能。此外，为了克服银纳米线的缺点（如高表面粗糙度以及基板与电极层之间的弱粘附性），采用剥离工艺制备了具有嵌入式结构的电极。通过弯曲、敲击和耐久性测试，证实这些多层电极比传统的银纳米线电极表现出更好的机械耐久性。制备了基于GCA/AgNW/GCA/cPAI电极的电阻式随机存取存储器，并证实了其对非易失性存储器的适用性。该存储器件在0.5 V时的开/关电流比约为10，表现出一次写入多次读取的特性，在多达300次扫描循环中保持这些存储特性。这些发现表明，GCA/AgNW/GCA/cPAI电极可作为下一代柔性非易失性存储器的柔性透明电极。
