“…In the last decade, we used the layer‐by‐layer (LbL) electrodeposition technique to prepare nanostructured conducting systems based on three alternated layers of poly(3,4‐ethylenedioxythiophene) (PEDOT) and poly( N ‐methylpyrrole) (PNMPy) , hereafter abbreviated 3l‐PEDOT/PNMPy (i.e., PEDOT/PNMPy/PEDOT). These multilayered materials showed better electrochemical properties and a higher ability to store charge than each of the two individual CPs and the corresponding copolymer, poly(3,4‐ethylenedioxythiophene‐ co ‐ N ‐methylpyrrole), hereafter named COP .…”

“…This synergy was proved considering three‐layered systems with different physical characteristics, composition, and/or polymerization conditions. These included systems that differ in the thickness of the layers (i.e., micro‐ and nanometric layers), systems prepared using dynamical conditions rather than conventional quiescent solutions , and systems modified with clays at the dielectric layer or with an octanethiol self‐assembled monolayer at the first PEDOT layer .…”

Multilayered films made with at least two different electroactive polymers, in which the least conducting one acts as a dielectric and separates the layers made with the other, behave as efficient electrodes for electrochemical supercapacitors. In this work, we present a simple strategy to develop improved multilayered electrodes with structured interfaces by enhancing the porosity of the dielectric. This has been achieved by growing sodium chloride crystals onto a conducting polymer layer and, after generation of all required layers using the layer‐by‐layer electrodeposition technique, salt crystals have been eliminated by water etching. Results from morphological and topographical studies on single‐layered poly(3,4‐ethylenedioxythiophene) (PEDOT), poly(N‐methylpyrrole) (PNMPy), and poly(3,4‐ethylenedioxythiophene‐co‐N‐methylpyrrole) (COP), as well as electrochemical investigations on bi‐layered films with enhanced porosity at the interface between the two layers, have been used to design new four‐layered electrodes. These consist in two layers of PEDOT separated by two layers of nanosegregated COP with a porous interface in the middle. Although the properties of the new four‐layered electrodes improve due to the porous interface, the highest specific capacitance corresponds to the two‐layered electrode in which two PEDOT layers are separated by an ultra‐porous interface.

This review deals with the progress in the field of polymer/fullerene nanocomposites particularly for the energy storage applications. Fullerene is a unique zero dimensional nanocarbon nanomaterial. Fullerene proposes several unique structural, optical, electrical, thermal, mechanical and other superior physical features to the polymeric nanocomposites. Consequently, the high performance polymer/fullerene nanocomposites result from the amalgamation of the unique characteristics of fullerene with the functional polymers. Here, the advancements in the polymer/fullerene nanocomposites regarding their processing and properties, especially the electrical conductivity, charge storage capacities, charge density, power density, charge-discharge, and cyclic performance have been discussed. Moreover, the future and challenging prospects have been summarized anticipating the progress in the field of polymer/fullerene-based energy storage technology.

Properties related with the charge storage capacity have been evaluated for threelayered films made with two sheets of poly(3,4-ethylenedioxythiophene) separated by an sheet of poly(N-methylpyrrole) or poly(3,4-ethylenedioxythiophene-co-Nmethylpyrrole) (3l-PEDOT/PNMPy or 3l-PEDOT/P(EDOT-co-NMPy), respectively).The most distinctive trend of the copolymer, which shows electrochemical properties intermediate between those of the two homopolymers, is the formation of a biphasic structure, EDOT-and NMPy-rich blocks organizing separately. The ability to exchange charge reversibly is higher for 3l-PEDOT/P(EDOT-co-NMPy) than for 3l-PEDOT/PNMPy, the electroactivity and electrostability of such two 3-layered films being significantly better than that of single-layered PEDOT. Advantages of 3l-PEDOT/P(EDOT-co-NMPy) are mainly based on the nanophase-segregated structure of the copolymer. Thus, the intermediate layer can be considered as random disposition of ultrathin dielectrics having nanometric length and width. In terms of charge storage, the intermediate layer of 3l-PEDOT/P(EDOT-co-NMPy) can be viewed as a thin reservoir filled of heterogeneously distributed nanometric supercapacitors that are connected in series among them and in parallel to the PEDOT layers. The superiority of 3l-PEDOT/P(EDOT-co-NMPy) as organic electrochemical supercapacitor compared to other 3-layered systems, has been proved by powering a red LED bulb.
