Owing to their extraordinary properties of π-conjugated polymers (π-CPs), such as light weight, structural versatility, ease of synthesis and environmentally friendly nature, they have attracted considerable attention as electrode material for metal-ion batteries (MIBs) and supercapacitors (SCPs). Recently, researchers have focused on developing nanostructured π-CPs and their composites with metal oxides and carbon-based materials to enhance the energy density and capacitive performance of MIBs and SCPs. Also, the researchers recently demonstrated various novel strategies to combine high electrical conductivity and high redox activity of different π-CPs. To reflect this fact, the present review investigates the current advancements in the synthesis of nanostructured π-CPs and their composites. Further, this review explores the recent development in different methods for the fabrication and design of π-CPs electrodes for MIBs and SCPs. In review, finally, the future prospects and challenges of π-CPs as an electrode materials for strategies for MIBs and SCPs are also presented.

An electrochemical sensor for paracetamol is executed by using conductive MOF (NiCu-CAT), which is synthesized by 2, 3, 6, 7, 10, 11-hexahydroxytriphenylene (HHTP) ligand. The utility of this 2D NiCu-CAT is measured by the detection of paracetamol, p-stacking within the MOF layers is essential to achieve high electrical conductivity, redox activity, and catalytic activity. In particular, NiCu-CAT demonstrated detection Limit of determination near 5μM for paracetamol through a wide concentration range (5–190 μM). The NiCu-CAT/GCE exhibits excellent reproducibility, stability, and interference for paracetamol.

Conjugated polymers with stabilizing coordination units for single-site catalytic centers are excellent candidates to minimize the use of expensive noble metal electrode materials. In this study, conjugated metallopolymer, POS[Cu], was synthesized and fully characterized by means of spectroscopical, electrochemical, and photophysical methods. The copper metallopolymer was found to be highly active for the electrocatalytic hydrogen generation (HER) in an aqueous solution at pH 7.4 and overpotentials at 300 mV vs. reversible hydrogen electrode (RHE). Compared to the platinum electrode, the obtained overpotential is only 100 mV higher. The photoelectrochemical tests revealed that the complexation of the conjugated polymer POS turned its intrinsically electron-accepting (p-type) properties into an electron-donor (n-type) with photocurrent responses ten times higher than the organic photoelectrode.

Abstract More than three decades after the major breakthrough in the efforts to develop intrinsic electric conductivity in conjugated polymers, which culminated in the year 2000 Nobel Prize for Shirakawa et al., conducting plastics hold the promise of providing a cost effective and unique alternative material solution for applications ranging from consumer electronics to optoelectronics, solar cells, lighting, memory, and a host of new photonic applications. It would not be an exaggeration to mention conducting polymers as the materials for the next century. The notion of conjugation as a pre-condition for a polymer to be made intrinsically conducting was challenged when a conjugated polymer such as natural rubber was doped to increase its electrical conductivity by more than 10 orders in magnitude. This discovery by Thakur et al., triggered a spate of investigations on the phenomenon and mechanism of conduction in nonconjugated polymers such as Elastomers. The discovery that rubbers could be doped like conjugated polymers raised the hope of finding extremely different micro applications hitherto unknown for natural rubber as well as synthetic rubbers. Investigations point toward the possibility of conducting rubbers, unlike the conjugated polymers having easy processability and cost effectiveness, finding wide applications in organic electronics and photonic applications. A critique of the early and current efforts in developing intrinsic electric conductivity in natural rubber as well as synthetic elastomers in the context of the investigations made by the authors in this direction is reviewed and presented.

Graphene oxide is an imperative modified form of graphene. Similar to graphene, graphene oxide has gained vast interest for the myriad of industrial applications. Conjugated polymers or conducting polymers are well known organic materials having conducting backbone. These polymers have semiconducting nature due to π-conjugation along the main chain. Doping and modification have been used to enhance the electrical conductivity of the conjugated polymers. The nanocomposites of the conjugated polymers have been reported with the nanocarbon nanofillers including graphene oxide. This review essentially presents the structure, properties, and advancements in the field of conducting polymer/graphene oxide nanocomposites. The facile synthesis, processability, and physical properties of the polymer/graphene oxide nanocomposites have been discussed. The conjugated polymer/graphene oxide nanocomposites have essential significance for the supercapacitors, solar cells, and anti-corrosion materials. Nevertheless, the further advanced properties and technical applications of the conjugated polymer/graphene oxide nanocomposites need to be explored to overcome the challenges related to the high performance.
