Interaction Forces between Adsorbed Layers of Associative Polymer
Bibliographic record
Abstract
We have measured normal quasi-equilibrium forces between adsorbed layers formed on hydrophilic surfaces in aqueous solutions of telechelic poly(ethylene oxide) end-terminated with octadecyl groups. At low polymer concentrations, c pol, a monolayer adsorbs, which has properties similar to the monolayer of adsorbed nonhydrophobized poly(ethylene oxide). At moderate concentrations of ca. c pol ≈ c cmc, a multilayer adsorbs onto the surface, which is presumably formed by micelles adsorbed onto the top of a monolayer. The adsorbed layers exhibit repulsion on approach and attraction on separation of the surfaces; the latter evolves after several/decompression cycles. The adhesion energy increases with the time that the compressed layers are maintained in contact and with the extent of compression of the adsorbed layers. We attribute the attraction between the adsorbed layers to bridging between the hydrophobic groups of molecules adsorbed onto opposite surfaces.

How this classification was reachedexpand
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.
