Conducting polymers have been widely used in electrochemical sensors as receptors of the sensing signal's analytes and transducers. Polypyrrole (PPy) conducting polymers are highlighted due to their good electrical conductive properties, ease in preparation, and flexibility of surface characteristics. The objective of this review paper is to discuss the theoretical background of the two main types of electrochemical detection: impedimetric and voltammetric analysis. It also reviews the application and results obtained from these two electrochemical detections when utilizing PPy as a based sensing material in electrochemical sensor. Finally, related aspects in electrochemical sensor construction using PPy will also be discussed. It is anticipated that this review will provide researchers, especially those without an electrochemical analysis background, with an easy-to-understand summary of the concepts and technologies used in electrochemical sensor research, particularly those interested in utilizing PPy as a based sensing material.
导电聚合物已被广泛应用于电化学传感器中,作为传感信号分析物的受体和换能器。聚吡咯(PPy)导电聚合物因其良好的导电性能、易于制备以及表面特性的灵活性而备受关注。本文综述的目的是讨论两种主要电化学检测方法的理论背景:阻抗分析和伏安分析。同时,还回顾了以PPy作为电化学传感器的基础传感材料时,这两种电化学检测方法的应用及所得结果。最后,还将讨论使用PPy构建电化学传感器的相关方面。预计本综述将为研究人员,尤其是那些没有电化学分析背景的人员,提供一份易于理解的电化学传感器研究中所使用概念和技术的总结,特别是那些对利用PPy作为基础传感材料感兴趣的人员。
