Photochromic superabsorbent polymers1
Bibliographic record
Abstract
Photochromic superabsorbent polymers (PSAPs) with a hydrophilic core and a photochromic shell were prepared by inverse suspension polymerization using acrylic acid (AA) and acrylamide (AM) as monomers, potassium persulfate as the initiator, N,N'-methylene bisacrylamide (BIS) as a cross-linker, sorbitan monostearate (Span60) as the dispersant, cyclohexane as the solvent and bis(methacryloylamino)azobenzene (AC) as the photochromic surface cross-linker. The polymer was characterized by NMR, infrared spectroscopy, differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Water absorption (Q) and the photoresponse of the PSAPs was investigated. The PSAPs prepared have excellent water absorption (2800 g g-1). When the sample is irradiated at 350 nm water expulsion from the swollen PSAPs was observed.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
