Novel Polymeric Surfadditives Synthesized via Atom Transfer Radical Polymerization and Their Surface Migration Properties
Bibliographic record
Abstract
Abstract Multi‐functional tri‐block copolymers having fluorinated and triethoxysilane side chains and polyacrylate backbone have been synthesized and used as surface‐active additives (termed as “surfadditive”) in molding and casting acrylic parts. The fluorinated block facilitates migration of surfadditive molecules to the part surface and the acrylate block provides rooting to the part matrix, while the silane block offers functionality to the part surface. This uniquely designed surfadditive allows surface functionalization and modification without post‐processing steps. This work reports the design and synthesis of surfadditives and demonstrates their surface enrichment in molding and cell casting of polymethylmethacrylate (PMMA) samples. The effects of processing temperature, surfadditive structure and concentration, as well as mold surface property on the surface modification are systematically investigated. magnified image

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.
