Plasma-functionalized multi-walled carbon nanotubes directly grown on stainless steel meshes as supercapacitor electrodes
Bibliographic record
Abstract
Abstract Multi-walled carbon nanotubes (MWCNTs) directly grown on a stainless steel mesh were functionalized using a fast, solvent-free radiofrequency (RF) plasma technique. Two different gas mixtures of Ar/C 2 H 6 /O 2 and Ar/C 2 H 6 /N 2 were used to add oxygen- and nitrogen-containing functional groups to the surface of MWCNTs. The binder-free forest-like MWCNTs before and after functionalization were tested as supercapacitor electrodes. The structural and electrochemical characteristics of the electrodes were evaluated. The RF power (10–30 W) and functionalization time (1–20 min) were optimized to achieve the highest capacitance. Both nitrogen- and oxygen-functionalized MWCNTs showed improved capacitive behavior due to the presence of the functional groups on the MWCNT surface. The highest capacitance was obtained for the MWCNT electrode functionalized with the RF plasma employing the Ar/C 2 H 6 /O 2 gas mixture at 20 W for 15 min, reaching the specific capacitance of 37.3 ± 1.1 mF cm −2 (196.3 ± 5.8 F g −1 ).

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.
