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.

P Type

A p-type thermoelectric conjugated polymer based on indacenodithiophene and benzothiadiazole is designed and synthesized by replacing normal aliphatic side chains (P1) with conjugated aromatic benzene substituents (P2). The introduced bulky substituent on P2 is detrimental to form the intensified packing of polymers, therefore, it hinders the efficient transporting of the charge carriers, eventually resulting in a lower conductivity compared to that of the polymers bearing aliphatic side chains (P1). These results reveal that the modification of side chains on conjugated polymers is crucial to rationally designed thermoelectric polymers with high performance.

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.
