The development of conducting polymer-based supercapacitors offers remarkable advantages, such as good ionic and electronic conductivity, ease of synthesis, low processing cost, and mechanical flexibility. 3,4-ethylenedioxythiophene (PEDOT) is a conducting polymer with robust chemical and environmental stability during storage and operation in an aqueous environment. Yet, improving its electrochemical capacitance and cycle life remains a challenge for high-performance supercapacitors exceeding the current state-of-the-art. The fabrication of PEDOT composites with carbon nanomaterials and metal oxides is the commonly used approach to enhance capacitance and stability. This work discusses a comparative study to fabricate highly stable PEDOT derivative electrodes with remarkable specific capacitance via a straightforward electrochemical polymerization technique. The hydroxymethyl PEDOT (PEDOTOH) doped with perchlorate in a dichloromethane (DCM) solvent (197 F g−1) exhibits superior performance compared to the polymer formed in an aqueous solution (124 F g−1). Furthermore, the electropolymerized PEDOTOH on flexible Au/Kapton substrates was assembled into a free-standing symmetrical supercapacitor in an agarose additive-free gel. The use of agarose gel electrolytes can offer easy handling, no leakage, moderate ionic conductivity, and flexibility for miniaturization and integration. The supercapacitor reached a specific capacitance of 36.96 F g−1 at a current density of 13.7 A g−1, an energy density of 14.96 Wh kg−1, and a power density of 22.2 kW kg−1 among the highest values reported for PEDOT-based supercapacitors. The self-standing supercapacitor achieves an industry-par capacitance retention of ∼98% after 10000 charge/discharge cycles at 10 A g−1. This study provides insights into the effect of solvents and electropolymerization modes on the polymer structure and its electrochemical properties toward high-performance supercapacitor devices.

“…Moreover, humans have not shown any inflammation when exposed to PEDOT; [101] therefore, PEDOTbased compounds have been widely applied for detecting biomolecules and many other electrochemically active species, such as antioxidants and medicines (Table 6). [112][113][114][115][116][117][118][119][120][121][122][123][124] Meng et al [112] proposed a composite based on GQDs and PEDOT for detecting rutin, which is a component in herbal medicines used for treating cardiovascular diseases. GQDs were obtained using a bottom-up method employing citric acid as organic precursor in the presence of NaOH.…”

Growing environmental and health demands along with the deficiency of conventional energy sources result in the need for alternative solutions in the field of energy storage and analyte detecting systems. To address these issues, a significant increase in research interest for novel composite materials has been observed in recent years. Conductive polymers and graphene‐based composites have emerged as promising electrode materials for supercapacitors and electrochemical sensors due to their improved electrochemical properties and versatility of the synthesis methods. The synergistic effect between the composite components and the unique morphology, physical and chemical characteristics result in enhanced performance of the electrochemical devices. In this review, we discuss recent trends and achievements in the synthesis, nanoarchitecture, and application of conductive polymers and graphene‐based composites in the field of supercapacitors and electrochemical sensors.

“…Recently, the number of works using the one-step approach has increased. This approach consists of a single step for obtaining the graphene-polymer composite through simultaneous synthesis and deposition (or alternating layers) of the graphene oxide and polymer species by simply modulating the applied electrochemical potential [6,41,78,[87][88][89][90][91][92][93][94][95].…”

The use of graphene and its derivatives in the development of electrochemical sensors has been growing in recent decades. Part of this success is due to the excellent characteristics of such materials, such as good electrical and mechanical properties and a large specific surface area. The formation of composites and nanocomposites with these two materials leads to better sensing performance compared to pure graphene and conductive polymers. The increased large specific surface area of the nanocomposites and the synergistic effect between graphene and conducting polymers is responsible for this interesting result. The most widely used methodologies for the synthesis of these materials are still based on chemical routes. However, electrochemical routes have emerged and are gaining space, affording advantages such as low cost and the promising possibility of modulation of the structural characteristics of composites. As a result, application in sensor devices can lead to increased sensitivity and decreased analysis cost. Thus, this review presents the main aspects for the construction of nanomaterials based on graphene oxide and conducting polymers, as well as the recent efforts made to apply this methodology in the development of sensors and biosensors.
