Coaxial electrospun nanofibers of poly(vinylidene fluoride)/polyaniline filled with multi‐walled carbon nanotubes
Bibliographic record
Abstract
Core‐shell nanofibers of poly (vinylidene fluoride)/polyaniline/multi‐walled carbon nanotubes (PVDF/PANi/MWCNTs) have been produced using the coaxial electrospinning technique. The nanofibers were semiconductive and had better piezoelectric properties than pure PVDF nanofibers. Piezoelectric PVDF nanofibers are capable of converting mechanical energy into electrical energy, which can be stored in charge storage devices. However, PVDF is not conductive and therefore, a conductive associate material is needed to transfer accumulated static charges into the capacitor. Fourier Transform Infrared (FTIR) spectroscopy and differential scanning calorimetry (DSC) were carried out to study the crystalline β‐phase of PVDF. There was an increase in β‐phase in the electrospun PVDF nanofibers filled with MWCNTs as compared with compression molded samples of neat PVDF. Incorporation of PANi as an intrinsically conductive polymer (ICP) and MWCNTs as conductive nanofiller helps the movement of static charges. Core‐shell nanofibers had conductivities of about seven orders of magnitude higher than simple electrospun nanofibers. POLYM. COMPOS., 35:1198–1203, 2014. © 2013 Society of Plastics Engineers

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.
