“…Electropolymerization of CMPTCBz.-Electropolymerization (EP) of CMPTCBz was studied through cyclic voltammetry coupled with electrochemical quartz crystal microbalance (CV-EQCM) and chronoamperometry techniques based on a systematic optimization process reported earlier by our group. 23 Solutions containing 0.01 M TCBz monomer in a solvent mixture of (DCM/ACN, 2:1) with 0.1 M lithium perchlorate electrolyte were prepared and the electropolymerization was performed in a three-electrode electrochemical cell. For CV-EQCM experiments, a gold coated quartz crystal electrode (AuQCE, CHI Instruments, USA) was used as the working electrode along with a non-aqueous Ag/Ag + reference electrode (CHI111/112 Reference Electrode) containing 0.1 M TEAClO 4 and 0.01 M silver nitrate (AgNO 3 ) in acetonitrile and a platinum wire as the auxiliary electrode.…”

The electropolymerization of Conjugated Microporous Poly-1,3,5-tris (N-carbazolyl) benzene (CMPTCBz) was investigated using a range of techniques. After the potential window was optimized for the electropolymerization process, a fixed potential was found to generate a CMPTCBz with minimal overoxidation and a high BET surface area. The CMPTCBz was mixed with sulfur and used in the optimized preparation of CMPTCBz-S cathodes. Coin cells were assembled with lithium metal used as the anode and electrochemically evaluated. Results showed that the CMPTCBz-S cathodes with different sulfur loadings have excellent charge/discharge cycling performance with initial discharge capacities ranging from 800 to 1400 mAh·g−1S and a capacity retention greater than 80% after 100 cycles. This is due to both the enhanced electrical conductivity of the cathode and physical confinement of the generated lithium-polysulfides inside the pores of the CMPTCBz. In a further experiment, a high sulfur loaded CMPTCBz-S cathode produced an initial discharge capacity of 548 mAh·g−1S and a capacity retention of 95% after 100 cycles using an organic electrolyte. Analysis using XPS showed that the sulfur to polysulfide conversion coupled with the dual functionality of the CMPTCBz in retaining the generated polysulfide are the key parameters for this superior performance.

“…The morphology of a polymer can significantly affect its conductive behaviour. Generally, polymers with more ordered and aligned structures provide more efficient charge transport, thus yielding higher conductivities compared with polymers with disordered structures [26,27]. Schütze et al discovered that polymer chains can form crystalline phases only for a regioregular head-to-tail/head-to-tail regularity, whereas for a head-to-head/tail-to-tail regularity, the system did not show any long-range order after annealing.…”

“…As a sulphur host that can be prepared via EP, polycarbazole (PCBZ) is considered a promising material, owing to its electrical conductivity of 10 −2 -10 −3 S cm −1 , low monomer cost, high chemical stability, and porous structure [27][28][29]. The carbazole monomer can undergo EP from either the 3-and 6-or 2-and 7-positions, rendering it extremely versatile [27,30].…”

Lithium–sulphur batteries (LiSBs) have garnered significant attention as the next-generation energy storage device because of their high theoretical energy density, low cost, and environmental friendliness. However, the undesirable “shuttle effect” by lithium polysulphides (LPSs) severely inhibits their practical application. To alleviate the shuttle effect, conductive polymers have been used to fabricate LiSBs owing to their improved electrically conducting pathways, flexible mechanical properties, and high affinity to LPSs, which allow the shuttle effect to be controlled. In this study, the applications of various conductive polymers prepared via the simple yet sophisticated electropolymerisation (EP) technology are systematically investigated based on the main components of LiSBs (cathodes, anodes, separators, and electrolytes). Finally, the potential application of EP technology in next-generation batteries is comprehensively discussed.

“…Besides, the less well-studied ones, such as polythiophene, polycarbazole, polydopamine, poly(p-phenylene vinylene), etc., have been reported for their applications in various fields. [90][91][92][93][94] Some cases, such as polyindole, are gathering attention because of specific properties like slower degradation than the competitors PPy and PANI. 51,95 A literature survey reveals that just few examples have been published for catalytic CO 2 conversion by such conducting polymers.…”

Conversion of carbon dioxide to value-added products (also termed as CO2 reduction reaction or CRR) is an exceptional route toward diminishing the amount of CO2 in the atmosphere and to help alleviate the energy and global warming crises. Within this framework, many types of research have been focused on introducing novel catalysts to reach an efficient system for the CRR. Conducting polymers (CPs) with appropriate electroactive characteristics have been used as effective catalysts for CRR for more than two decades. Polypyrrole (PPy) and polyaniline (PANI) are two of the most commonly studied CPs. Accordingly, this work presents a comprehensive review of the electrocatalytic performance of conductive polymers, including their composites, for CO2 reduction. A comparative approach is also followed to indicate their advantages and disadvantages over common metal-based heterogeneous electrocatalysts. The important perspectives and key challenges for developing these catalysts are also discussed.
