Abstract Much recent work has focused on improving the processibility and electrocapacitive performance of conducting polymer-based materials for energy related applications. The key mechanism of conducting polymers as supercapacitor materials is driven by the rapid charging and discharging processes that involve mass transport of the counter ions insertion/ejection within the polymer structure, where ion diffusion is usually the limiting step on the efficiency of the conducting polymer capacitor. Here, we report a facile method for the green fabrication of polypyrrole microspheres (PPy-MSs) and poly (3, 4-ethylenedioxythiophene) microspheres (PEDOT-MSs) with good processability, intact morphology and large active surface for enhanced ion interchange processes, without using surfactant and highly irritant or toxic organic solvents during the synthetic process. The structure and morphology of the PPy-MSs and PEDOT-MSs were characterized by means of SEM, EDX, TEM and FTIR. Both PPy-MSs and PEDOT-MSs showed intact microsphere structures with greatly improved water dispersity and processability. More importantly, facilated by the large active surface and inter-microsphere space for ions diffusion, both the PPy-MSs and PEDOT-MSs showed a signiciantly enhanced electrical capacitive performance of 242 F g−1 and 91.2 F g−1, repsectively (i.e. 10 and 1.51 times in specific capacitance than the randomly structured PPy and PEDOT). This innovative approach not only addresses fundamental issues in fabrication of high performance processable microstructured conducting polymers, but also makes progress in delivering water processable conducting polymers that could be potentially used for fabrication of printed electronic devices.

易于合成高度可加工和水分散的聚吡咯和聚（3,4-亚乙基二氧噻吩）微球以增强超级电容性能

摘要 最近的许多工作都集中在提高用于能源相关应用的基于聚合物的导电材料的可加工性和电容性能。导电聚合物作为超级电容器材料的关键机制是由快速充电和放电过程驱动的，该过程涉及聚合物结构内反离子插入/排出的质量传输，其中离子扩散通常是导电聚合物电容器效率的限制步骤. 在这里，我们报告了一种用于绿色制造聚吡咯微球 (PPy-MS) 和聚 (3, 4-亚乙基二氧噻吩) 微球 (PEDOT-MS) 的简便方法，具有良好的加工性、完整的形态和大的活性表面，用于增强离子交换过程，在合成过程中不使用表面活性剂和高刺激性或有毒的有机溶剂。PPy-MSs 和 PEDOT-MSs 的结构和形貌通过 SEM、EDX、TEM 和 FTIR 表征。PPy-MSs 和 PEDOT-MSs 都显示出完整的微球结构，水分散性和可加工性大大提高。更重要的是，在大的活性表面和用于离子扩散的微球间空间的促进下，PPy-MSs 和 PEDOT-MSs 分别显示出 242 F g-1 和 91.2 F g-1 的显着增强的电容性能（即比电容是随机结构的 PPy 和 PEDOT 的 10 倍和 1.51 倍）。这种创新方法不仅解决了高性能可加工微结构导电聚合物制造中的基本问题，
