介绍了以银/氯化银或喹氢酮为内参比电极的Kapton基平面微型和半微量电位型传感器的设计、制作和性能特点。根据在恶劣环境中的性能，对由传统的和各种改性的聚氯乙烯基质浇铸的含有不同pH敏感离子载体的离子选择膜进行了排序。定量评估了不同聚氯乙烯薄膜与聚酰亚胺涂层Kapton基板的粘接强度随制备工艺和样品溶液接触的变化。电极的长期稳定性是通过传感器的分析参数在一段时间内的变化以及通过测定其传感膜的电阻变化来表征的。
The design, fabrication and performance characteristics of Kapton-based planar mini and semimicro potentiometric sensors with an Ag/AgCl or a quinhydrone-based redox internal reference electrode are described. The ion-selective membranes cast from conventional and various modified PVC matrices and containing different pH-sensitive ionophores are ranked on the basis of their performances in hostile environments. The adhesive bonding strength of the different PVC membranes to the polyimide-coated Kapton substrate was quantitatively evaluated as a function of fabrication procedure and sample solution contact. The long-term stability of the electrodes was characterized by the alterations of the analytical parameters of the sensors over a period of time, as well as by determining the resistance changes of their sensing membranes.
