Special Issue Information

Dear Colleagues,

The environmental crisis is at its worst stage, mainly due to human dependency on fossil fuel-based energy production. Additionally, numerous new substances are being produced, used, and, afterwards, disposed of directly into the environment regardless of the consequences and without the required technology for their quantification. Thus, it is important to research and design new materials that improve the performance of devices for the conversion, storage, and supply of clean energy, and for the detection of pollutants. In particular, there is a global interest for the development of novel materials with applications for clean energy production systems (fuel cells, photovoltaics), energy storage devices (batteries, capacitors), and sensors. In this regard, in alternative to classic inorganic materials, conducting polymers have stood out as suitable materials in the abovementioned applications. Conducting polymers are less toxic, more abundant, versatile materials if compared to inorganic-based materials. Thus, several strategies for the preparation and application of conducting polymers have been developed during the last half century. Nowadays, nanostructured conducting polymers (including composites between conducting polymers and nanomaterials or nanometric structured conducting polymers) have gained significant attention from scientific community due to the enhancement of typical properties. If compared to bulk morphology, nanostructured conducting polymers usually present higher surface area, increased electrical conductivity, greater charge storage capacity, enhanced durability, faster charge transference, among others. Therefore, numerous new methods for the preparation and application of nanostructured conducting polymers are being published showing outstanding performances on energy technologies and sensors, such as those mentioned.  

Understanding their potentiality on the improvement of key-technologies required to counter environmental crisis, this Special Issue of Polymers invites contributions addressing several aspects of nanostructured conducting polymers, such as novel preparation methods (chemical or electrochemical), novel monomer polymerization of nanostructures, fundamental characterization (thermodynamics and kinetics), computational modeling, and application on energy technologies and sensors. The above list is only indicative and by no means exhaustive; any original research or review article dealing with any aspect of nanostructured conducting polymers is welcome. We hope that these contributions will address a variety of systems, including linear and nonlinear conducting polymer architectures, conducting polymer blends, copolymers, nanoparticle-conducting polymer composites, any shape of nanostructured conducting polymer (sphere, wire, bar, plates, among others), and its applications (fuel cells, photovoltaics, light-emitting diodes, batteries, capacitors, sensors, among others).

In this work, a conducting polymer (CP) was obtained through three electrochemical procedures to study its effect on the development of an electrochemical immunosensor for the detection of immunoglobulin G (IgG-Ag) by square wave voltammetry (SWV). The glassy carbon electrode modified with poly indol-6-carboxylic acid (6-PICA) applied the cyclic voltammetry technique presented a more homogeneous size distribution of nanowires with greater adherence allowing the direct immobilization of the antibodies (IgG-Ab) to detect the biomarker IgG-Ag. Additionally, 6-PICA presents the most stable and reproducible electrochemical response used as an analytical signal for developing a label-free electrochemical immunosensor. The different steps in obtaining the electrochemical immunosensor were characterized by FESEM, FTIR, cyclic voltammetry, electrochemical impedance spectroscopy, and SWV. Optimal conditions to improve performance, stability, and reproducibility in the immunosensing platform were achieved. The prepared immunosensor has a linear detection range of 2.0–16.0 ng·mL−1 with a low detection limit of 0.8 ng·mL−1. The immunosensing platform performance depends on the orientation of the IgG-Ab, favoring the formation of the immuno-complex with an affinity constant (Ka) of 4.32 × 109 M−1, which has great potential to be used as point of care testing (POCT) device for the rapid detection of biomarkers.

Due to the energy requirements for various human activities, and the need for a substantial change in the energy matrix, it is important to research and design new materials that allow the availability of appropriate technologies. In this sense, together with proposals that advocate a reduction in the conversion, storage, and feeding of clean energies, such as fuel cells and electrochemical capacitors energy consumption, there is an approach that is based on the development of better applications for and batteries. An alternative to commonly used inorganic materials is conducting polymers (CP). Strategies based on the formation of composite materials and nanostructures allow outstanding performances in electrochemical energy storage devices such as those mentioned. Particularly, the nanostructuring of CP stands out because, in the last two decades, there has been an important evolution in the design of various types of nanostructures, with a strong focus on their synergistic combination with other types of materials. This bibliographic compilation reviews state of the art in this area, with a special focus on how nanostructured CP would contribute to the search for new materials for the development of energy storage devices, based mainly on the morphology they present and on their versatility to be combined with other materials, which allows notable improvements in aspects such as reduction in ionic diffusion trajectories and electronic transport, optimization of spaces for ion penetration, a greater number of electrochemically active sites and better stability in charge/discharge cycles.
