Abstract

fetched live from OpenAlex

Abstract Crystallization occurs in processing i ‐PP‐GnP nanocomposites, and these nanocomposites have the potential to replace traditional fillers and be used to fabricate advanced materials and technology. Therefore, this subject was comprehensively investigated by applying a recent crystallization model, non‐isothermal DSC experiments, Raman spectroscopy, and WAXRD. The multi‐layer GnP‐induced nucleation and the crystal growth rates were modelled. The overall modelling effort generated new insights, results, and explanations. This study confirmed and elucidated, or refuted several published conclusions. It has also been reported that the present model can pursue differences in catalyst‐mediated i ‐PP backbone defects (stereo and regio) by simulating the relative crystallization profile and determining the crystallization kinetic triplet ( n , k o , and E a ). The multiple roles played by GnP were underscored, which exceed what the related literature currently reports. The Raman and XRD work revealed the interaction between GnP and i ‐PP. The shear‐induced dispersion of GnP that occurs during extrusion significantly affected i ‐PP crystal size distribution. The present approach can also assess the effects of catalyst type and structure, and backbone defect types and their distribution on the non‐isothermal crystallization of, in general, polyolefin blends and nanocomposites.

Not 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.
