Characterization of a PEDOT:PSS Electrolytic Device Using an in situ Spectroelectrochemical Technique
Bibliographic record
Abstract
PEDOT:PSS, a conjugated polymer, has demonstrated great potential in emerging applications due to its variable conductivity and spectral attenuation. However, it is necessary to understand the relationship between these properties and the doping state of PEDOT:PSS. This work uses an in situ spectroelectrochemical experiment to measure conductance and spectral attenuation of PEDOT:PSS while being dedoped quasistatically with lithium ions. Results show a reversible decrease in conductivity during dedoping with a maximum on/off ratio of 2500. The relationship between conductivity and doping state displays a sigmoidal shape with minimum conductivity at ~1.2mC of intercalated charge. Migration speed of lithium through PEDOT:PSS was found to have a power-law speed-time relationship, where the exponent was on average 0.715 for applied voltages of 2V-5V. This work provides important parameters to facilitate simulation of complex PEDOT:PSS polymer-electrolyte devices.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
