<scp>Processing‐structure–property</scp> relationships in the fabrication of extrusion electroactive poly(vinylidenefluoride) filaments
Bibliographic record
Abstract
Abstract Poly(vinylidenefluoride) with enhanced electroactive properties is of great interest in energy harvesting and sensing applications. This study aims to elucidate the effects of processing parameters in extrusion, using a desktop extruder or a microcompounder, on the polymorphism of the fabricated poly(vinylidenefluoride) filaments. All samples were characterized by differential scanning calorimetry, Fourier‐transform infrared spectroscopy, and electromechanical testing. Statistical analyses were conducted to correlate the processing parameters with the poly(vinylidenefluoride) filaments' crystal structures. Experimental results revealed that the optimal extrusion temperature at 220°C and stretching ratio of 4.5 to 6.5 would yield poly(vinylidenefluoride) filaments with a degree of crystallinity of up to 58% of which 80% is β‐phase crystals. The finding of this manuscript has the potential to promote the use of poly(vinylidenefluoride) filaments in the fused filament fabrication.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
