Effect of the First Coagulating Bath Composing on the Structure of PES Membrane
Bibliographic record
Abstract
Make PES flat-sheet style membrane through the method of dual-bath coagulation method. Change the composing of the first coagulating bath and make the casting membrane liquid stay in the first coagulating bath for enough time and control the surface and interior structure of the membrane at the same time. Study the interior and exterior structure when the DMAc mass fraction of first coagulating bath is among 0%-70%, and find out with the increase of mass fraction, the interior structure of membrane transits from the form of finger pore to the form of spongy pore, and when the mass fraction of the first coagulating bath achieves 70%, there is no structure with the form of finger pore, but the opening structure on the membrane surface appears when the mass fraction is 60% and increases with the increase of concentration. When the mass fraction of the first coagulating bath is among 0%-50%, the pure water flux of the membrane decreases with the concentration, and the rejection ratio of BSA change less, and when the concentration of the first coagulating bath exceeds 60% and the openings appear on the membrane surface, the pure water flux would ascend but the rejection ratio would markedly decrease.

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.
