论文摘要
微型和平面超级电容器的进步导致在便携式和可弯曲的电子设备中产生小型化的储能装置。微型电容器具有独特的电化学性能，例如高功率密度，快速充电，较长的周期寿命和高安全性。微型占领器的制造过程的减少时间和成本是微型制作技术的重要因素。在这项工作中，提出了简单，可扩展性和成本效益的氧化石墨烯@聚苯胺柔性微型摄影剂。我们发现，在PET底物上制造互插的微电极图案时；通过激光照射，同时同时执行了氧化石墨烯的还原和导电聚合物的生长。电容为72 mF/cm2，在0.035ma/cm2电流密度下为72 MF/cm2。这些高电容的微型摄影剂表现出良好的稳定性，并且在0.7 mA/cm2电流密度下1000个循环后保留了超过93.5％的电容。
The advances in micro-size and in-plane supercapacitors lead to produce the miniaturizing energy storage devices in portable and bendable electronics. Micro-supercapacitors have unique electrochemical performance, such as high power density, fast charging, long cycle life, and high safety. The reduction time and cost in the fabrication processes of micro-supercapacitors are important factors in micro-fabrication technology. In this work, a simple, scalable and cost-effective fabrication of interdigitated reduced graphene oxide@polyaniline flexible micro-supercapacitors is presented. We found that in fabricating the interdigitated microelectrode patterns on PET substrate; the reduction of graphene oxide and growth of conducting polymer are rapidly performed simultaneously in one step by laser irradiation. The capacitance was 72 mF/cm2 at 0.035mA/cm2 current density. These high capacitance micro-supercapacitors demonstrate good stability and more than 93.5% of the capacitance retain after 1000 cycles at 0.7 mA/cm2 current density.
