Surface Morphology and Properties of Ternary Polymer Blends: Effect of the Migration of Minor Components
Bibliographic record
Abstract
In this work, the surface morphology and properties of ternary polymer blends and the migration of minor component molecules to the top surface layer of the films were studied. We used polystyrene (PS), poly(butylene adipate-co-terephthalate), polycaprolactone, poly(methyl methacrylate), and polylactide as second minor phases in a blend of polyethylene terephthalate-poly(ethylene glycol) (PET-PEG). The morphology of the ternary systems predicted using the spreading coefficient and relative interfacial energy concepts was confirmed by scanning electron microscopy images. The surface characterization results showed a higher rate of migration of PEG to the polymer-air interface in the systems with a nonwetting morphology and the highest in the PET-PS-PEG blend. Atomic force microscopy images suggested that the high surface hydrophilicity of the PET-PS-PEG blend is due to a dendritic pattern of PEG crystals on the film surface, which were not observed for the other samples.

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.
