Solution Processed Coating of Polyolefin on Melamine Foams to Fabricate Tough Oil Superabsorbents
Bibliographic record
Abstract
Abstract Oil superabsorbent porous materials having rapid oil/water separation, high oil absorption capacity, good mechanical strength, superior recyclability, low costs, and manufacture scalability are still highly desired for oil spill cleanup applications. In this work, commercially available melamine foams are modified through dip‐coating by polyolefin/toluene solution. All characterizations confirm that polyolefin is successfully coated on surfaces of the melamine foam skeleton, giving a micro‐nano scale hierarchical architecture. The modified foams absorb oil and repel water with a water contact angle higher than 130°. The absorption capacities of the modified foams for various oil and solvents are in the range of 42.6–116.5 g g−1. The retention of sorption capacity remains above 95% after 100 cycles of sorption–squeezing. Mechanical testing reveals that the compressive‐recovery property is kept and the tensile strains at break of the modified foams are improved compared to their original counterparts. This method is facile, inexpensive, and can be easily scaled‐up.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
