This study presents the fabrication and characterization of flexible Schottky diodes based on silver (Ag) and polyaniline (PAni) layers, constructed on a recyclable poly(ethylene--methyl acrylate--glycidyl methacrylate) terpolymer (PE-MA-GM) substrate. The fabrication process involved compression molding of the PE-MA-GM resin substrate and patterning of PAni layers using aluminum masks, followed by the deposition of Ag electrodes. Electrical characterization revealed stable current-voltage (I-V) characteristics at room temperature and under varying operating temperatures. Furthermore, the devices exhibited decent performance under mechanical bending at angles of 40°, and 60°, demonstrating robustness against mechanical stress. Additionally, we recycled entire devices and reconstructed Ag/PAni on the recycled substrate, achieving I-V characteristics comparable to the original measurements. While the fabrication methods used in this study were nonstandard, our preliminary findings underscore the potential of Ag/PAni Schottky diodes integrated onto a flexible and recyclable PE-MA-GM substrate. The results demonstrate promising performance metrics, with stable electrical behavior across varying operating conditions. This work offers an alternative approach to advancing the development of flexible and sustainable electronic systems. It paves the way for future studies focused on optimizing device performance, improving scalability, and expanding applications in wearable and environmentally conscious technologies.
本研究展示了基于银（Ag）和聚苯胺（PAni）层的柔性肖特基二极管的制造与特性，这些二极管构建在可回收的聚（乙烯-甲基丙烯酸甲酯-甲基丙烯酸缩水甘油酯）三元共聚物（PE-MA-GM）基板上。制造过程包括对PE-MA-GM树脂基板进行压缩成型，使用铝掩膜对PAni层进行图案化，随后沉积Ag电极。电学特性表明，在室温及不同工作温度下，电流-电压（I-V）特性稳定。此外，这些器件在40°和60°的机械弯曲角度下表现出良好的性能，证明了其对机械应力的鲁棒性。此外，我们回收了整个器件，并在回收的基板上重新构建了Ag/PAni，获得了与原始测量结果相当的I-V特性。虽然本研究中使用的制造方法不标准，但我们的初步研究结果强调了集成在柔性且可回收的PE-MA-GM基板上的Ag/PAni肖特基二极管的潜力。结果显示出有前景的性能指标，在不同工作条件下具有稳定的电学行为。这项工作为推进柔性和可持续电子系统的发展提供了一种替代方法。它为未来专注于优化器件性能、提高可扩展性以及在可穿戴和环保技术中扩展应用的研究铺平了道路。
