Electrochemical Characterization of Actuatable polyHIPE/PEDOT Scaffolds

Check if the same lab product or an alternative is used in the 5 most similar protocols

Electrochemical characterization was carried out
by cyclic voltammetry (CV) at a scan rate of 10 mV/s from 0.8 V/-0.8
V for polyHIPE/PEDOT scaffolds of known dimensions using a VSP potentiometer
(Interface1010E, Gamry instruments) in a classical three-electrode
configuration in a degassed (Argon) PBS solution and complete cell
culture medium (DMEM + 10% FCS). Ag wire was used as a pseudoreference
(Ref.) and glassy carbon rod as a counter electrode (CE). The measured
currents were normalized by the geometric surface area of the polyHIPE/PEDOT
scaffold used as a working electrode (WE). Actuation of the polyHIPE/PEDOT
scaffolds, monitored using a CLSM in reflection mode, was induced
by alternating the potential at the scaffold from 0.8 to −0.4
V for 60 s at each oxidation and reduction step over 3 cycles in total
using a VSP potentiometer (Interface1010E, Gamry Instruments). The
confocal images were processed by using ImageJ-FIJI software. Their
intensity values were falsely colored with a “rainbow”
lookup table. With this color scheme, low-intensity pixels appeared
in blue colors and high-intensity pixels in hot colors, such as orange
and red. This approach aimed to enhance the visualization of the scaffold’s
actuation.

Electrochemical Characterization of Catalysts

All electrochemical measurements were performed by using a Interface 1010E potentiostat (Gamry Instruments, Warminster, PA, USA). The OER tests were carried out in a standard 1 M KOH (pH = 13.6) solution. For the UOR tests, 0.5 M urea was added to the alkaline solution. Linear sweep voltammetry (LSV) curves were recorded with a scan rate of 5 mV/s, and iR-correction was applied using the current interrupt (CI) method. Electrochemical impedance spectroscopy (EIS) measurements were conducted in the potential static mode, using frequencies ranging from 1 to 10⁵ Hz and an oscillation amplitude of 10 mV at an overpotential of 450 mV vs. Hg/HgO (balanced with 1 M KOH). The stability of the electrocatalyst was tested using chronopotentiometry at a constant current density of 100 mA cm⁻² for a duration of 20 hours. To account for the pH effects, the potentials were converted to the reversible hydrogen electrode (RHE) scale using the Nernst equation (E vs. RHE = E vs. ref + 0.059 × pH + 0.114 V). The potential of the Hg/HgO electrode was also calibrated against a Pt|H₂ (g) electrode in the 1 M KOH electrolyte using a multimeter [21 (link)], which showed a potential of 0.916 V (Figure S1), consistent with the calculation mentioned above.

Redox properties and HOMO and LUMO energy levels were investigated by cyclic voltammetry (CV) using a 5 × 10^–4 M solution of BX dyes in 0.1 M tetrabutylammonium hexafluorophosphate, acting as supporting electrolyte, in acetonitrile. A 25 ml measuring solution was poured into a 50 ml conical shape electrochemical vessel and bubbled with 5.0 N Ar for deaeration. The measurements were performed in a three-electrode setup with a 0.0314 cm² glassy carbon (GC) working electrode, a Pt spring counter electrode, and Pt wire as a pseudoreference electrode. The working electrode potential was normalized against Fc/Fc⁺ redox couple as the intersolvental standard recommended by IUPAC^{46 (link)}. The GC electrode surface was restored before every measurement series and, whenever necessary, by mechanical polishing with artificial diamond powder on the wet polishing cloth. The CV curves have been registered on a Gamry Interface 1010 E potentiostat–galvanostat.
UV–Vis absorption spectra were obtained on a Shimadzu UV-3600 Plus UV–Vis–NIR Spectrophotometer in a 1 cm path-length quartz cell using 10^–5 M acetonitrile solutions of investigated dyes.

Impedance was
measured with an Interface 1010E (Gamry Instruments, Warminster, Pennsylvania,
USA), from 2 MHz to 0.1 Hz with 10 mV AC voltage. Each electrolyte
specimen was tested in a CR 2032 coin-cell holder between 15.5 mm
diameter stainless steel disks (MTI Corporation, Richmond, California,
USA) that served as ion-blocking electrodes. Except for the minimum
time necessary for mechanical testing or EIS measurements, all CPEs
were kept in nitrogen-purged storage. An equivalent circuit model
R1–(R2/Q2)–Q3 was used for fitting of impedance measurements
and determination of bulk resistance using impedance analysis software
(Zfit from BioLogic, Seyssinet-Pariset, France). R₁ represents the contact resistance; R₂ and Q₂ represent the bulk
resistance and bulk capacitance of the electrolyte, respectively;
and Q₃ represents the capacitance between
the electrolyte and the stainless steel spacers. Ionic conductivity,
κ, is calculated from bulk resistance R_b = R₂ according to the formula
κ = h/(R_bA), where h is the thickness of the electrolyte
and A is the cross-sectional area.

Electrochemical measurements were performed to characterize SIROF stability and recording capabilities over time before and after delivering higher current amplitudes through the electrodes. Both in vitro and in vivo electrode impedance measurements were recorded sequentially over the period under different stimulating current thresholds. All measurements were taken using a Gamry Interface 1010E (Gamry Instruments, Warminster, PA USA) in a standard three-electrode configuration (working, counter and reference).

The electrochemical performance of the samples was evaluated using standard CR2032-type coin half-cells assembled in a glovebox in a dry, high-purity argon atmosphere. Each CR2032-type coin comprised a working electrode, potassium-foil anode, glass-fiber separator (Whatman, GF/B), and electrolyte (0.8 M KPF₆/ethylene carbonate (EC)/diethyl carbonate (DEC), 1 : 1 by volume).
The working electrode was prepared as follows: the prepared sample, acetylene black, and polyvinylidene fluoride (PVDF) binder were mixed with mass proportions 80 : 10 : 10 in N-methyl pyrrolidone (NMP). The mixed slurry was coated on a Cu foil and dried under vacuum at 120 °C overnight. Then, the working electrodes were punched out and weighed. The amount of active substance is about 1.5–2.0 mg cm².
Galvanostatic charge–discharge tests were performed on a BTS 4000 battery cycler (Shenzhen NEWARE Electronics Co. Ltd., Shenzhen, China) at 25 °C in the potential range 0.01–3 V (vs. K/K⁺). The current density and specific capacity of the sample were calculated according to the mass of carbon prepared in the working electrode. An electrochemical workstation (Interface 1010E, Gamry Instruments, Warminster, USA) was used to perform cyclic voltammetry (CV) over the potential range 0.01–3.0 V, as well as electrochemical impedance spectroscopy (EIS) over the frequency range 10⁵–10⁻³ Hz at 25 °C.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
