“…Clearly, the analytical performance of this PPy-based electrode is somewhat inferior to the classical pH glass electrode and polyaniline (vide infra). Electrochemically synthesized PPy doped with bicarbonate was applied as pH electrode in a Severinghaus CO 2 sensor by Binag et al [107].…”

Conducting polymers, i.e., electroactive conjugated polymers, are useful both as ion-to-electron transducers and as sensing membranes in solid-state ion-selective electrodes. Recent achievements over the last few years have resulted in significant improvements of the analytical performance of solid-contact ion-selective electrodes (solid-contact ISEs) based on conducting polymers as ion-to-electron transducer combined with polymeric ion-selective membranes. A significant amount of research has also been devoted to solid-state ISEs based on conducting polymers as the sensing membrane. This review gives a brief summary of the progress in the area in recent years.

“…Hence, polymer sensors are multifunctional, and in general, polymer-based sensors are used in an array. Tongola et al (2003) fabricated a pH indicating polypyrrole-based CO 2 sensor. Carbon dioxide diffusing through the polypyrrole membrane forms carbonic acid, which dissociates and alters the pH of the internal electrolyte.…”

In the food and agricultural industry, sensors are being used for process control, monitoring quality, and assessing safety. There is a growing demand for carbon dioxide (CO 2 ) sensors in the bulk food storage sector, because CO 2 sensors can be used to detect incipient spoilage and to assess CO 2 levels in modified-atmosphere packages and storage structures. The market potential for reliable and inexpensive CO 2 sensors is huge because of a wide range of applications in the agri-food industry. This review synthesizes information about the types of CO 2 sensors, analyzes their detection processes, provides a broad overview of the innovative research on the development of sensors, sensing mechanisms, and their characteristics, and outlines future possibilities for use of CO 2 sensors.

“…Polypyrrole (Ppy) is a characteristic-conducting polymer and promising sensing material employed in various chemical sensors [12][13][14][15][16][17][18]. The bicarbonate-doped Ppy was coated as the material of pH-indicator electrode to probe carbon dioxide [12].…”

“…The bicarbonate-doped Ppy was coated as the material of pH-indicator electrode to probe carbon dioxide [12]. Pyrrole was polymerized with the matrix of cross-linking polyvinyl alcohol (PVA) to form a composite sensing material and that could detect NH 3 [13].…”
