Assembling Conductive PEBA Copolymer at the Continuous Interface in Ternary Polymer Systems: Morphology and Resistivity
Bibliographic record
Abstract
Two ternary blend systems of low-density polyethylene/poly(ether- block -amide)/polyethylene terephthalate (LDPE/PEBA/PET) and LDPE/PEBA/polyvinylidene fluoride (PVDF) are prepared by melt blending to thermodynamically assemble the ionically conductive PEBA copolymer at the continuous interface. The LDPE/PEBA/PET blend demonstrates weak partial wetting and a novel morphology transition to complete wetting was observed as the PEBA composition increases from 3% to about 10%. The phenomena can be explained by a mechanism based on the competition between dewetting and coalescence of the PEBA phase at the interface. In the completely wet LDPE/PEBA/PVDF system, a minimum concentration is required to form intact PEBA layers with a thickness of ∼100 nm. Assembling PEBA at the interface of the ternary systems results in the formation of conductive pathways of very low percolation thresholds and thus leads to a significant reduction in the resistivity for both ternary systems as compared to binary blends with PEBA. A particularly sharp drop in resistivity is observed for the complete wetting morphology of LDPE/PEBA/PVDF.

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.
