“…Various inorganics and macromolecules have been used to prepare PEMs. [ 237–245 ] According to their microstructure, they can be classified as zero‐dimension (e.g., particles and spheres), one‐dimension (e.g., fibers, tubes, wires, rods), two‐dimension (e.g., sheets), and three‐dimension (e.g., network structure). Using sulfonated polystyrene microspheres as a template, Wang et al.…”

Polymer electrode materials (PEMs) have become a hot research topic for lithium-ion batteries (LIBs) owing to their high energy density, tunable structure, and flexibility. They are regarded as a category of promising alternatives to conventional inorganic materials because of their abundant and green resources. Currently, conducting polymers, carbonyl polymers, radical polymers, sulfide polymers, and imine polymers as five kinds of PEMs are studied extensively. This review introduces the latest research progress of PEMs for LIBs from the perspectives of molecular structure, redox mechanism, and electrochemical performance. The synthesis mechanisms and methods are outlined to guide the future design of PEMs. However, the practical application of PEMs is limited by their insufficient conductivity, structural instability, and high solubility. Aiming at these obstacles, reasonable optimization strategies are discussed, including the modification of molecular structure, the control of micromorphology, and the composite of carbon materials. Finally, the development trends and prospects of PEMs are put forward.

“…Moreover, the combination of CPs and CNTs can prevent the agglomeration of CNTs by steric hindrance and electrostatic interactions. The nanocomposite used as a modifying material can enhance the selectivity of the electrode by providing more chemically active sites for the target substances [28][29][30][31]. Although CPs/CNTs nanocomposite-modified electrodes have proven to be a potential method for sensing tyrosine, dopamine, glucose, ascorbic acid, and other organic substances, the fabrication of reliable and selective L-lactic acid sensors based on CPs/CNTs nanocomposites has not been reported.…”

In this study, a novel cobalt polyphthalocyanine/carboxylic acid functionalized multiwalled carbon nanotube nanocomposite (CoPPc/MWCNTs-COOH) to detect lactic acid was successfully fabricated. The nanocomposite was systematically characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, ultraviolet–visible absorption spectroscopy, and X-ray photoelectron spectroscopy. The nanocomposite provided excellent conductivity for effective charge transfer and avoided the agglomeration of MWCNTs-COOH. The electrochemical surface area, diffusion coefficient and electron transfer resistance of the CoPPc/MWCNTs-COOH glassy carbon electrode (CoPPc/MWCNTs-COOH/GCE) were calculated as A = 0.49 cm2, D = 9.22 × 10−5 cm2/s, and Rct = 200 Ω, respectively. The lactic acid sensing performance of the CoPPc/MWCNTs-COOH was evaluated using cyclic voltammetry in 0.1 M PBS (pH 4). The results demonstrated that the novel electrode exhibited excellent electrochemical performance toward lactic acid reduction over a wide concentration range (10 to 240 μM), with a low detection limit (2 μM (S/N = 3)), and a reasonable selectivity against various interferents (ascorbic acid, uric acid, dopamine, sodium chloride, glucose, and hydrogen peroxide). Additionally, the electrode was also successfully applied to quantify lactic acid in rice wine samples, showing great promise for rapid monitoring applications.

Summary In this study, we followed a facile method to grow well‐aligned PANI nanostructures on S‐doped reduced graphene oxide nanosheets (SPANI/S‐rGO) using hydrothermal method combined with soft template polymerization of aniline where naphthalene sulfonic acid is used as a dopant for PANI as well as the soft template. The effect of using different wt% of S‐rGO on the structural, morphology, and electrochemical performance of SPANI/S‐rGO composites has been evaluated. Supercapacitor fabricated using SPANI/S‐rGO10 (10 wt% of S‐rGO) composite based electrodes delivered a high specific capacitance of 347.5 F/g at a current density of 1 A/g in symmetrical cell design (the specific capacitance was calculated based on a single electrode). Only 11% of its initial capacitance is lost after 2500 cycles at a current density of 2 A/g. The enhanced performance is attributed to the optimum loading of S‐rGO in designing binary composite, well‐aligned growth of SPANI nanostructures on S‐rGO sheets, and synergistic effect of both S‐rGO and SPANI. The facile synthesized SPANI/S‐rGO composite electrode material with the aforementioned features is considered to be a promising candidate for a high‐performance supercapacitor.
