Special Issue Information

Dear Colleagues,

Since their serendipitous discovery, electroconducting polymers (CPs) have represented a significant revolution in fields ranging from materials science to electronics, from aerospace to biomedicine. The unique combination of electroconductivity, flexibility, redox activity, stability, processability, environmental friendliness, and doping dependence behaviour deem CPs the perfect bridge between the worlds of organic chemistry and material science, enabling the development of advanced devices, sensors, and technologies that were previously difficult or impossible to achieve with conventional materials. Chemical composition, synthesis methods, and processing conditions are crucial to tailoring CPs’ properties for specific applications, driving ongoing innovation in this field. Materials based on CPs can have a wide variety of applications, for example, biomimetic, smart materials, renewable energy sources, various sensors and biosensors, packaging etc.

This Special Issue welcomes original research articles and reviews on (but not limited to) the synthesis and characterization of crystalline CP-based materials. Researchers from academia and industry are furthermore encouraged to share their latest investigations and their original results regarding properties as well as potential or effective applications of this class of materials.

In this work, hierarchically porous composites were prepared in the form of activated carbon cloth (CC) Busofit T–1–055 filled with an electrically conductive polymer, polyaniline (PANI), for use as pseudocapacitive electrodes of electrochemical supercapacitors (SCs). CC fibers have high nanoporosity and specific surface area, so it was possible to deposit (via the chemical oxidative polymerization of aniline) a significant amount of PANI on them in the form of a thin layer mainly located on the inner surface of the pores. Such morphology of the composite made allowed the combining of the high capacitive characteristics of PANI with the reversibility of electrochemical processes, high columbic efficiency and cyclic stability rather typical for carbon materials of double-layer SCs. The highest capacitance of composite electrodes of about 4.54 F/cm2 with high cyclic stability (no more than 8% of capacity loss after 2000 charge–discharge cycles with a current density of 10 A/cm2) and columbic efficiency (up to 98%) was achieved in 3 M H2SO4 electrolyte solution when PANI was synthesized from an aniline hydrochloride solution with a concentration of 0.25 M. Trasatti analysis revealed that 27% of specific capacitance corresponded to pseudocapacitance, and 73% to the double-layer capacitance. Full article
