Combinatorial Polyelectrolyte Multilayer Film Fabrication
Bibliographic record
Abstract
A combinatorial strategy for the fabrication of a library of polyelectrolyte multilayer films is presented in this paper. This innovative approach involves the parallel formation of polyelectrolyte multilayer films in the individual wells of polystyrene microtitre plates under various deposition conditions. The progress of film formation was monitored via the intensity of the UV-vis absorbance of one of the depositing polyelectrolytes using a conventional microplate reader. We demonstrate the utility of this technique by building a library of 120 distinct polyelectrolyte multilayer films. Both the primer layer composition and salt content of the polyeletrolyte solutions were systematically varied in the preparation of films of nine bilayers. Film growth did not follow a linear adsorption regime for the first three bilayers regardless of the composition of the primer layer. We observed that increasing the sodium chloride concentration in the polyelectrolyte solutions resulted in increased polyelectrolyte absorption for all the conditions studied. The approach presented here is a convenient method of producing and characterizing multiple films rapidly and reproducibly, making it a valuable tool for optimizing film fabrication.

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.
