研究了用聚四氟乙烯（PTFE）粉末和全氟聚醚（PFPE）油修饰碳糊电极（CPE）。将这两种氟化材料与石墨粉简单混合。将伏安行为与非氟化材料的伏安行为进行比较，即，聚乙烯（PE）粉末和液体石蜡（LP）油。与非氟化CPE相比，含PTFE和PFPE的CPE具有更宽的极化电位窗口和更低的充电电流。当测试溶液的离子强度足够低时，观察到反应物与氟化电极表面之间的静电相互作用。含有PTFE和PFPE的CPE在四氢呋喃（THF）溶液中是稳定的，而其他CPE则不稳定，这是由于非氟化材料的溶解。©作者2020.由ECSJ发布。这是一篇开放获取的文章，根据知识共享署名非商业性相同方式共享4.0许可证（CC BY-NC-SA，http：//creativecommons.org/licenses/by-nc-sa/4.0/）的条款分发，该许可证允许在任何媒体上通过相同方式进行非商业性重复使用，分发和复制，前提是原始作品被正确引用。如需获得商业再利用的许可，请发送电子邮件给相应的作者。[DOI：10.5796/电化学，20 -65150]。
A carbon paste electrode (CPE) modified with polytetrafluoroethylene (PTFE) powder and perfluoropolyether (PFPE) oil was studied. These two fluorinated materials were simply mixed with graphite powder. The voltammetric behavior was compared with those of non-fluorinated materials, i.e., polyethylene (PE) powder and liquid paraffin (LP) oil. The CPE with PTFE and PFPE gave a wider polarizable potential window and a lower charging current than the non-fluorinated CPEs. When the ionic strength of the test solution was sufficiently low, the electrostatic interaction between the reactant and the fluorinated electrode surface was observed. The CPE with PTFE and PFPE was stable in a tetrahydrofuran (THF) solution, whereas other CPEs were not, due to the dissolution of the non-fluorinated materials. © The Author(s) 2020.
