Zeolite ZSM5-Filled PVDF Hollow Fiber Mixed Matrix Membranes for Efficient Carbon Dioxide Removal via Membrane Contactor
Bibliographic record
Abstract
ZSM5 zeolite-filled PVDF mixed matrix membranes (MMMs) were wet spun and used for CO 2 absorption in a contactor system. The properties of ZSM5 were analytically characterized. SEM images revealed the fully asymmetric structure of membranes, in which the creation of finger-like macrovoids was promoted with increasing filler loading. A significant increase in gas permeance was observed, which was associated with the porosity increase of the membrane surface despite the decrease in surface pore size. The surface roughness, wettability resistance, and mechanical stability of membranes were also considerably improved by filler loading. A CO 2 absorption test with water revealed a higher CO 2 flux of MMMs than that of the plain membrane. Peak absorption flux of 5.80 × 10 –3 mol m –2 s –1 was achieved at a liquid velocity of 1.2 m s –1 for 5 wt % ZSM5/PVDF membrane (MZ5), which was nearly 177% higher than that of neat PVDF and also surpassed that of several commercial and in-house made membranes. The mass transfer resistance of the MMMs was also considerably lower than that of PVDF.

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.
