A redox exchange mechanism between potassium perruthenate (KRuO4) and the functional groups of selected polymers is used here to induce RuO2 into and onto conductive polymer nanowires by simply soaking the polymer nanowire arrays in KRuO4 solution. Conductive polymer nanowire arrays of polypyrrole (PPY) and poly(3,4-ethylenedioxythiophene) (PEDOT) were studied in this work. SEM and TEM results ...

Composites of poly(3,4-ethylenedioxypyrrole) or PEDOP and poly(3,4-ethylenedioxythiophene) or PEDOT enwrapped Sb2S3 nanorods have been synthesized for the first time for use as supercapacitor electrodes. Hydrothermally synthesized Sb2S3 nanorods, several microns in length and 50-150 nm wide, offer high surface area and serve as a scaffold for coating conducting polymers, and are a viable altern...

For wearable applications such as electronic skin and biosensors, stretchable conductors are required (∼30% strain to follow the extension). Owing its high conductivity, good flexibility, low cost, ease of processing, poly(3,4-ethylenedioxythiophene) (PEDOT) appears a promising candidate. However, destructive cracks come out above 10% in case PEDOT:PSS, most common form PEDOT. Different strateg...

Sulfonated carbon nanotubes (S-CNTs) and sulfonated graphene (S-Gra) with superior dispersibility were successfully prepared to modify poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) for applications in polymer solar cells (PSCs). The synergetic effect between S-CNTs/S-Gra and PEDOT:PSS could remove excess insulating PSS chains leading to an obvious phase separation between ...

A voltammetric microsensor has been developed for the simultaneous assay of ascorbic (AA) and uric (UA) acids in aqueous solution. Theelectrode surface hasbeenmodifiedbymeansof electropolymerized conductive poly(3,4-ethylenedioxythiophene) PEDOT organic films. The electrocatalytic activity of the interface was dependent on the electropolymerization parameters inducing change in the structure an...

We present a method to chemically deposit a conductive polymer, poly(3,4-ethylenedioxythiophene) (PEDOT), on acellularized muscle tissue constructs. Morphology and structure of the deposition was characterized using optical and scanning electron microscopies (SEM). The micrographs showed elongated, smooth, tubular PEDOT structures completely penetrating and surrounding the tissue fibers. The ch...

Dual amide hydrogen bond crosslinked and strengthened high strength supramolecular polymer conductive hydrogels were fabricated by simply in situ doping poly (N-acryloyl glycinamide-co-2-acrylamide-2-methylpropanesulfonic) (PNAGA-PAMPS) hydrogels with PEDOT/PSS. The nonswellable conductive hydrogels in PBS demonstrated high mechanical performances-0.22-0.58 MPa tensile strength, 1.02-7.62 MPa c...

UNLABELLED Thiophene moieties have been attached to Si microwires (Si MWs) by a two-step chlorination/alkylation reaction method. X-ray photoelectron spectroscopy indicated that saturation of the surface occurred after 30 min of reaction time. Electrical measurements using a standard probe station indicated that the junction between individual thiophene-functionalized Si MWs and the conducting ...

The combination of high capacity redox active pendent groups and conducting polymers, realized in conducting redox polymers (CRPs), provides materials with high charge storage capacity that are electronically conducting which makes CRPs attractive for electrical energy storage applications. In this report, six polythiophene and poly(3,4-ethylenedioxythiophene)(PEDOT)-based CRPs with a diethyl t...

Abstract: Composites of multiwall carbon nanotubes (MWNTs), electrically conducting polymers like polyaniline (PANI), and poly (3, 4-ethylenedioxythiophene)–polystyrene sulfonic acid (PEDOT: PSS) were prepared by following solution casting method. MWCNTs were functionalized with oxidative acid (5M HNO3) treatment schemes to improve the adhesion between the polymer and carbon nanotubes by a п-п ...
