Abstract

fetched live from OpenAlex

Morphologies of ultrathin films of nine poly(ε-caprolactone)/polymer miscible and immiscible binary blends have been investigated under isothermal crystallization conditions by real time atomic force microscopy, optical microscopy, and electron diffraction techniques. It was found that the truncated lozenge-shape morphology of the pure poly(ε-caprolactone) (PCL) crystals is modified in miscible blends, forming regular or inverted S- or C-shaped crystals, the curvature depending on the nature of the second polymer and increasing with blend composition. Moreover, the growth rate decreases with the addition of the second polymer following the same order as the crystal curvature: PVC > CPE(48%) > SAN(25%) > PC > SAN(9.5%) > PVME. In contrast, for immiscible blends, no significant changes in kinetics and morphology were observed since a constant crystal growth rate and the same truncated lozenge-shape morphology as pure PCL crystals are obtained at all compositions. Kinetic and morphological changes in miscible blends are discussed in terms of PCL/polymer intermolecular interactions since the growth rate decreases and the curvature increases with the addition of polymers of increasing interactions.

Teacher imitation

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.
