Abstract
Abstract Multilayer thin films prepared from weak polyelectrolytes can exhibit a rich suite of anomalous physicochemical properties. One of the major factors that influence the properties of such films is the acid/base chemistry of the weak functional groups of the poly- electrolytes. In fact, the apparent dissociation constants of weak polyelectrolytes can shift by as much as 1–4 pH units upon incorporation into multilayer films from that in dilute solution. Here, we discuss this variability in the dissociation behavior of polyelectrolytes in multilayer films, and how it relates to understanding the diversity in the physicochemical properties observed for films assembled from the same polyelectrolytes, but under different pH conditions. In turn, we review some of the recent research that attempts to take advantage of the pH-tunable properties of multilayer films for a variety of applications.

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 it
