Abstract
A simple method has been implemented to create flexible, uniform graphene–polypyrrole composite films using a pulsed electropolymerization technique for supercapacitor electrodes. Applying the pseudocapacitive contribution of conformal redox-active polypyrrole to graphene supercapacitor electrodes results in high performance while still maintaining the inherent flexibility of graphene films. Specific capacitances as high as 237 F/g were obtained for a moderate total deposition time of only 120 s, which is approximately four times higher than the blank scaffold, graphene films. This flexible supercapacitor film exhibited very high energy and power densities with values of ∼33 Wh/kg and ∼1184 W/kg, respectively, at a scan rate of 0.01 V/s. This increase was attributed to the favorable nucleation of new polymer chains at defects on the graphene surface, which become less favorable as defect sites are occupied by existing polymer nanoparticles.

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 it
