“…On humans, the toxicological impact is high because they persist for long periods, producing several health problems such as skin damage and necrosis [ 290 ]. These kinds of compounds are chemically stable and poorly biodegradable because of their nitro-substituted aromatic structure [ 291 ]. However, one advantage for the application of electrochemical methods is the easily reducible nitro groups allowing development sensors with good sensitivity, selectivity, and fast response [ 292 ].…”

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.

“…The suspension of an MWCNT composite reinforced with sulphonated poly(3,4-ethylenedioxytiophene) (S-PEDOT) was utilized in the voltammetric determination of nitrobenzene [99]. The authors functionalized a conducting polymer (PEDOT) with a sulphonate group to obtain a conjugated polyelectrolyte, with a goal of achieving good conductance and polyelectrolyte properties.…”

The development of sensing coatings, as important sensor elements that integrate functionality, simplicity, chemical stability, and physical stability, has been shown to play a major role in electrochemical sensing system development trends. Simple and versatile assembling procedures and scalability make polyelectrolytes highly convenient for use in electrochemical sensing applications. Polyelectrolytes are mainly used in electrochemical sensor architectures for entrapping (incorporation, immobilization, etc.) various materials into sensing layers. These materials can often increase sensitivity, selectivity, and electronic communications with the electrode substrate, and they can mediate electron transfer between an analyte and transducer. Analytical performance can be significantly improved by the synergistic effect of materials (sensing material, transducer, and mediator) present in these composites. As most reported methods for the preparation of polyelectrolyte-based sensing layers are layer-by-layer and casting/coating methods, this review focuses on the use of the latter methods in the development of electrochemical sensors within the last decade. In contrast to many reviews related to electrochemical sensors that feature polyelectrolytes, this review is focused on architectures of sensing layers and the role of polyelectrolytes in the development of sensing systems. Additionally, the role of polyelectrolytes in the preparation and modification of various nanoparticles, nanoprobes, reporter probes, nanobeads, etc. that are used in electrochemical sensing systems is also reviewed.

In this paper, a new model has been proposed to estimate the electrical conductivity of polymer carbon nanotube (CNT) nanocomposites based on the conventional power-law model and Halpin-Tsai formulation. Halpin-Tsai model was originally presented to calculate the tensile modulus of composites, which can be modified for the estimation of the electrical conductivity by replacing the electrical parameters. The nature of the "b" exponent in the power-law model is defined according to CNT dimensions, CNT electrical conductivity, and the interphase thickness, and also the impacts of these parameters on the "b" and the electrical conductivity of nanocomposite are taken into consideration. The developed model interprets that the electrical conductivity of polymer-CNT nanocomposite increases as the concentration, length, and electrical conductivity of CNT and the interphase thickness increase. Furthermore, reduction in CNT diameter and waviness results in the growth of nanocomposite electrical conductivity. In order to validate the developed model, nanocomposite samples with different volume fractions were produced by the solid-state technique of the melt-blending method. The results of calculations and experimental procedures show good agreement.
