The interest for biodegradable electronic devices is rapidly increasing for application in the field of wearable electronics, precision agriculture, biomedicine, and environmental monitoring. Energy storage devices integrated on polymeric substrates are of particular interest to enable the large-scale on field use of complex devices. This work presents a novel class of eco-friendly supercapacitors based on biodegradable poly(3-hydroxybutyrrate) PHB, ionic liquids, and cluster-assembled gold electrodes. By electrochemical characterization, we demonstrate the possibility of tuning the supercapacitor energetic performance according to the type and amount of the ionic liquid employed. Our devices based on hydrophobic plastic materials are stable under cyclic operation and resistant to moisture exposure.
可生物降解电子设备在可穿戴电子、精准农业、生物医学和环境监测领域的应用兴趣正在迅速增加。集成在聚合物基板上的储能设备对于实现复杂设备的大规模现场使用尤为重要。这项工作展示了一类基于可生物降解的聚（3-羟基丁酸酯）PHB、离子液体和团簇组装金电极的新型环保超级电容器。通过电化学表征，我们证明了根据所用离子液体的类型和数量来调节超级电容器能量性能的可能性。我们基于疏水塑料材料的设备在循环操作下稳定且耐潮湿环境。
