In recent years, due to the environmental impact caused by electronic waste, decomposable components have become one of the most important topics in the world. In this study, the carrageenan material extracted from red algae was used as the resistance-switching layer of electronic components, and potassium was added to the carrageenan as a substrate (CK). CK has the advantages of excellent mechanical properties, transparency, and decomposability. In addition, the In/carrageenan/Ag/CK (ICACK) device exhibits good memory properties with a high ON/OFF ratio exceeding 10 and a retention time exceeding 10 s. Due to the doping of potassium ions, the ICACK element has a fairly good bending performance. Although bending or stretching under a small radius of curvature will not have a great impact on the electrical performance, it shows that in the future wearable or good potential in the field of implantable devices.
近年来，由于电子废弃物对环境造成的影响，可分解组件已成为全球最重要的议题之一。在本研究中，从红藻中提取的角叉菜胶材料被用作电子组件的电阻切换层，并将钾添加到角叉菜胶中作为基底（CK）。CK具有优异的机械性能、透明度和可分解性等优点。此外，In/角叉菜胶/Ag/CK（ICACK）器件表现出良好的记忆特性，开/关比高达10以上，保持时间超过10秒。由于钾离子的掺杂，ICACK元件具有相当好的弯曲性能。尽管在小曲率半径下弯曲或拉伸不会对电性能产生很大影响，但这表明其在未来可穿戴设备或植入式设备领域具有良好的潜力。
