Superamphiphobic Diblock Copolymer Coatings
Bibliographic record
Abstract
A new diblock copolymer, poly[3-(triisopropyloxysilyl)propyl methacrylate]- block -poly[2-(perfluorooctyl)ethyl methacrylate] (P1 or PIPSMA- b -PFOEMA), that bore a fluorinated PFOEMA block and a sol–gel forming PIPSMA block was synthesized by sequential anionic polymerization and was characterized. P1 was then used to coat silica particles. Factors affecting the amount of P1 grafted onto the silica particles by the sol–gel reactions of the PIPSMA block were investigated, and the coating conditions were optimized. At sufficiently high P1-to-silica mass feed ratios, P1 chemically grafted onto silica surfaces to yield a monolayer. While monolayer formation was supported by results of thermogravimetric analyses, dynamic light scattering, atomic force microscopy, and transmission electron microscopy, our X-ray photoelectron spectroscopy study suggested that the monolayer was topped by the PFOEMA block. Depositing these particles onto microscope slides and printing paper yielded rugged silica films. These films were superamphiphobic, and both water and oil droplets (cooking oil, diodomethane, and hexadecane) possessed large contact angles. The films composed of P1-coated silica particles had substantial resistance to etching by aqueous NaOH solution.

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.
