Abstract
Novel charged–surface modifying macromolecules (cSMMs) were synthesized and incorporated into polyethersulfone(PES) hollow fiber membranes for water separation application. The macromolecules were synthesized with diisocynate, polypropylene oxide and poly(ethylene glycol)–hydroxybenzene sulfonate (PEG–HBS). In this study, the surface of polyethersulfone hollow fiber membranes prepared by the phase inversion method was modified using 1 wt.% of SMM and 22 wt.% PES concentration in the polymer casting solution. The effect of cSMM on PES hollow fiber membrane modification was investigated. Elemental analysis shows enrichment of oxygen and sulfone on the modified PES membrane bulk properties. In addition, the glass transition temperature confirms the miscibility of the cSMM in PES. Important relations between surface characteristics due to SMM modification with the PES membrane for water separation performance with respect to XPS characterization also highlighted.

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
