“…Previous reviews are available that discuss various strategies employed to achieve highperformance CP-based pseudocapacitors. [19,20,[59][60][61][62][63][64][65][66] A common theme is to introduce an ionically conductive component to form blends or composites with the electrically conductive CPs. The composite typically serves as robust mechanical support to prevent structural degradation during operation.…”

Conjugated polyelectrolytes (CPEs) are characterized by an electronically delocalized backbone bearing ionic functionalities. These features lead to properties relevant for use in energy‐storing pseudocapacitor devices, including ionic conductivity, water processability, gel‐formation, and formation of polaronic species stabilized by electrostatic interactions. In this Perspective, the basis for evaluating the figures of merit for pseudocapacitors is provided, together with the techniques used for their evaluation. The general utility and challenges encountered with neutral conjugated polymers are then discussed. Finally, recent advances on the use of CPEs in pseudocapacitor devices are reviewed. The article is concluded by discussing how their miscibility in aqueous media permits the incorporation of CPEs in living materials that are capable of switching function from extraction of energy from bacterial metabolic pathways to pseudocapacitor energy storage.

“…Within this context, ECPs have demonstrated an enormous potential in terms of high specific capacitance (values ranging from 300 to 800 F·g −1 [ 6 , 7 , 8 ] depending on electrochemical performance conditions), high conductivity (up to 103 S·cm −1 ) [ 7 , 9 ], light weight and flexibility [ 10 ], relatively fast charge-discharge processes [ 11 ], easy processing and relative low-cost [ 12 , 13 ], and environmental friendliness [ 14 ]. Thus, from the synthesis perspective, the electrochemical deposition of ECPs by means of electrochemical techniques based on galvanostatic [ 15 , 16 , 17 ], potentiostatic [ 18 , 19 ], and potentiodynamic [ 20 , 21 ] methods, recently opened up new perspectives to design and develop a great variety of polymer morphologies.…”

This work deals with electroactive conducting polymers (ECPs) used as a complementary component on purely capacitive silicon nanowires protected by a 3 nm alumina layer. Accordingly, in this work, we use a fast and simple deposition method to create a pseudocapacitive material based on the electropolymerization in aqueous micellar media (SDS and SDBS 0.01 M) of hydroxymethyl-EDOT (EDOT-OH) onto 3 nm alumina-coated silicon nanowires (Al3@SiNWs). The composite material displays remarkable capacitive behavior with a specific capacitance of 4.75 mF·cm−2 at a current density of 19 µA·cm−2 in aqueous Na2SO4 electrolyte.

“…Conducting polymers (CPs) are an important class of organic multifunctional materials that exhibit specific physical and electrical properties. The possibility of fine-tuning their optical and conducting properties makes them promising candidates for a wide range of applications, including the fields of energy [ 10 , 11 , 12 ], electronics [ 13 , 14 ], catalysis [ 15 ], electromagnetic interference shielding [ 16 , 17 , 18 ], biomedicine [ 7 , 8 ], and sensors [ 3 , 7 , 8 , 12 , 19 , 20 , 21 , 22 ]. CPs usually exhibit relatively low conductivity (~10 −8 –10 −3 S·m −1 ) in their pure state; nonetheless, this property can be effectively enhanced to ~100–10 6 S·m −1 either by chemical or electrochemical doping in the case of intrinsic CPs or by physical mixing with other electro-conducting species such as metal or metal oxide nanoparticles, metal-organic frameworks (MOFs), and carbon-based nanomaterials, among others [ 19 , 20 , 23 ].…”

Lignosulfonate-Based Conducting Flexible Polymeric Membranes for Liquid Sensing Applications

et al. 2021

In this study, lignosulfonate (LS) from the acid sulfite pulping of eucalypt wood was used to synthesize LS-based polyurethanes (PUs) doped with multiwalled carbon nanotubes (MWCNTs) within the range of 0.1–1.4% w/w, yielding a unique conducting copolymer composite, which was employed as a sensitive material for all-solid-state potentiometric chemical sensors. LS-based PUs doped with 1.0% w/w MWCNTs exhibited relevant electrical conductivity suitable for sensor applications. The LS-based potentiometric sensor displayed a near-Nernstian or super-Nernstian response to a wide range of transition metals, including Cu(II), Zn(II), Cd(II), Cr(III), Cr(VI), Hg(II), and Ag(I) at pH 7 and Cr(VI) at pH 2. It also exhibited a redox response to the Fe(II)/(III) redox pair at pH 2. Unlike other lignin-based potentiometric sensors in similar composite materials, this LS-based flexible polymeric membrane did not show irreversible complexation with Hg(II). Only a weak response toward ionic liquids, [C2mim]Cl and ChCl, was registered. Unlike LS-based composites comprising MWCNTs, those doped with graphene oxide (GO), reduced GO (rGO), and graphite (Gr) did not reveal the same electrical conductivity, even with loads up to 10% (w/w), in the polymer composite. This fact is associated, at least partially, with the different filler dispersion abilities within the polymeric matrix.
