Isotropic and anisotropic interphases in polymer systems
Bibliographic record
Abstract
A polyisoprene-poly 4-vinyl pyridine (PIP/P4VP) diblock polymer has been used as adsorbate and adhesive on PVC and PMMA substrates. The diblock polymer is able to undergo surface restructuring, the rubber constituent being preferentially surface localized during contact with non-polar media, the P4VP moiety becoming dominant when in contact with polar media. Acid-base characterization shows that specific acid-base interaction takes place in the PVC-PIP/P4VP pairing, but not in the PMMA case. The block copolymer chain configuration on PVC is independent of the adsorbed layer thickness, creating an isotropic interphase. Adsorbed on PMMA, the copolymer chain undergoes a configurational change, creating an anisotropic interphase. Bond strength data indicate that the presence of acid-base interactions and of isotropic interphases is beneficial to both the initial value and to the retention of bond characteristics during accelerated aging.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
