Surface difference of novel fluorinated polyacrylate latex prepared with different surfactants
Bibliographic record
Abstract
The novel fluorinated polyacrylate latex was successfully prepared by emulsion polymerisation of perfluorononylene allyl ether (PFAE) with butyl acrylate (BA) and methyl methacrylate (MMA) initiated by potassium persulphate (KPS) in the water with different surfactants. PFAE was synthesised from the intermediate perfluoro nonene and 3-allyl alcohol as staring reactants. Films of the novel fluorinated polyacrylate latex were prepared by coating the latex directly on the clean glass sheet and allowed to dry at 80°C in a bake oven. The structure of the novel fluorinated polyacrylate latex was investigated by Fourier transform infrared spectrometry. Surface difference of novel fluorinated polyacrylate latex prepared with different surfactants was studied. Results show that the latex prepared with sodium dodecyl benzene sulphonate surfactant has smaller particle size, contact angle and lower surface tension. The latex prepared with sodium 2-hydroxy-3-(methacryloyloxy) propane-1-sulphonate surfactant has larger particle size, higher surface tension and larger contact angle.

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.
