“…757 Therefore, it is of great importance to develop a sensitive method to monitor the concentration of hydrazine in real samples. PEDOT based sensors, PEDOT/lignosulfonate (PEDOT/LS) composites electrogenerated on a glassy carbon electrode by galvanostatic polymerization, 758 can be combined to produce materials showing remarkable electrocatalytic activity toward the oxidation of hydrazine. The electrooxidation of hydrazine occurs at a potential of 0.2 V (Figure 50).…”

Conducting polymers (CPs), thanks to their unique properties, structures made on-demand, new composite mixtures, and possibility of deposit on a surface by chemical, physical, or electrochemical methodologies, have shown in the last years a renaissance and have been widely used in important fields of chemistry and materials science. Due to the extent of the literature on CPs, this review, after a concise introduction about the interrelationship between electrochemistry and conducting polymers, is focused exclusively on the following applications: energy (energy storage devices and solar cells), use in environmental remediation (anion and cation trapping, electrocatalytic reduction/oxidation of pollutants on CP based electrodes, and adsorption of pollutants) and finally electroanalysis as chemical sensors in solution, gas phase, and chiral molecules. This review is expected to be comprehensive, authoritative, and useful to the chemical community interested in CPs and their applications.

“…Until the past decade lignin and its composites had only been explored for electrochemical detection. 70,72,162 The charge storage property of lignin was first investigated in 2012 by Milczarek and Inganas; they identified that, with the improvement in its electronic and ionic properties by PPy, the charge storage of lignin could be enabled from its quinone sites. The synergy and compositional variation of a conductive conjugated polymer PPy and LS saw the charge capacity ranging with the thickness of the electrodes; the thin film electrode had a charge storage capacity of 70−75 mAh g −1 .…”

The demand for the development of electrochemical energy storage systems from abundant, renewable, eco-friendly, and cost-effective materials has been the focal and driving point in the advancement of electronic devices. This task and demand can be addressed with a resource that is abundant and possesses the attributes of being developed into efficient electrochemical energy storage systems. Lignin and cellulose, which are collectively known as lignocellulose, are the two most abundant biopolymers available, and they possess the attributes and the qualities to meet this demand. Lignocellulose biopolymers possess unique characteristics such as mechanical flexibility, porosity, and tunability because of their abundant and diverse functional groups. These qualities enable suitable pairing with electronically conducting polymers as enhanced materials for the development of sustainable energy storage devices. This Review highlights the challenges and the utilization of lignocellulose with electronically conducting polymers in supercapacitors applications and battery applications in various capacities as electrodes, separators, binders, and electrolytes.

Electrochemical Sensors Based on Conducting Polymers for the Aqueous Detection of Biologically Relevant Molecules

et al. 2021

Electrochemical sensors appear as low-cost, rapid, easy to use, and in situ devices for determination of diverse analytes in a liquid solution. In that context, conducting polymers are much-explored sensor building materials because of their semiconductivity, structural versatility, multiple synthetic pathways, and stability in environmental conditions. In this state-of-the-art review, synthetic processes, morphological characterization, and nanostructure formation are analyzed for relevant literature about electrochemical sensors based on conducting polymers for the determination of molecules that (i) have a fundamental role in the human body function regulation, and (ii) are considered as water emergent pollutants. Special focus is put on the different types of micro- and nanostructures generated for the polymer itself or the combination with different materials in a composite, and how the rough morphology of the conducting polymers based electrochemical sensors affect their limit of detection. Polypyrroles, polyanilines, and polythiophenes appear as the most recurrent conducting polymers for the construction of electrochemical sensors. These conducting polymers are usually built starting from bifunctional precursor monomers resulting in linear and branched polymer structures; however, opportunities for sensitivity enhancement in electrochemical sensors have been recently reported by using conjugated microporous polymers synthesized from multifunctional monomers.
