Degradable Microgel Wet-Strength Adhesives: A Route to Enhanced Paper Recycling
Bibliographic record
Abstract
Demonstrated is a new approach to cellulose fiber-based materials that are strong when wet, yet can be recycled after exposure to a weak reducing agent. Poly( N -isopropylacrylamide- co -acrylic acid) microgels were transformed into wet cellulose adhesives by incorporation of hydrazide groups that can form hydrazone linkages to oxidized cellulose. Reductant responsivity was obtained by introducing cleavable disulfide linkages, either in the chains tethering the adhesive hydrazide groups, or by using disulfide cross-links in the microgels. Both types of disulfide derivatives gave about 75% reduction in cellulose wet adhesion after exposure to a reductant. Truly sustainable wood-fiber replacements for plastic packaging must be insensitive to water while being fully recyclable; this work demonstrates two routes to reversible wet cellulose adhesives, facilitating recycling.

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.
