Abstract
Abstract Effective antibacterial modification of poly(ethylene terephthalate) (PET) was achieved by forming a surface thermoplastic semi‐interpenetrating network of polyacrylamide (PAM) and PET, followed by converting the immobilized amides to N ‐halamine. The regenerability of N ‐halamine on PAM‐modified PET was significantly influenced by the cross‐linkers used to form the network. Through Fourier transform infrared spectroscopy and nitrogen content analysis of the materials for up to 29 regeneration cycles, it was found that breaking down of the PAM network in chlorination accounted for the loss of regenerability. The relationship between antibacterial efficacy and N ‐halamine concentration was also studied. Compared with N , N ′‐methylenebisacrylamide and 2‐ethyleneglycol diacrylate, cross‐linker divinylbenzene can generate more durable PAM network. After 29 regeneration cycles, the PAM‐divinylbenzene network‐modified PET was still able to provide 100% reduction of healthcare‐associated methicillin‐resistant Staphylococcus aureus in 20 min contact. © 2010 Wiley Periodicals, Inc.

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
