Abstract

fetched live from OpenAlex

This work investigates the adhesion dynamics and interfacial behavior of ethylene vinyl alcohol (EVOH) and a commercial tie layer based on polyethylene-grafted maleic anhydride (PE-g-MA) films, manufactured through a multilayer co-extrusion process. The interfacial morphology is significantly influenced by the co-extrusion parameters and the cooling conditions. Moreover, increasing the co-extrusion temperature leads to an increase in interface thickness and induces greater entanglement, thereby enhancing adhesion. Additionally, water quenching caused the interdiffusion of the adjacent polymers across the interface to freeze and, in turn, resulted in a strong adhesion between EVOH and the tie layer. The corresponding failure mode is predominantly cohesive, particularly at elevated temperatures (60 °C and 80 °C), where we observed a 250 % improvement in the peel strength. Conversely, air cooling (slow) yielded adhesive failures irrespective of the peel test temperature. This study demonstrates the importance of understanding the process and the interfacial behavior that drives the adhesion mechanism between EVOH and PE-g-MA at room and high temperatures.

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.
