Surface Modification of Wood Fiber and Preparation of a Wood Fiber–Polypropylene Hybrid by In situ Polymerization
Bibliographic record
Abstract
Abstract The surface functionalization of wood fiber was performed by chemical modification with bi‐functional organo‐silane 7‐octenyldimethylchlorosilane (7‐ODMCS) and mono‐functional organo‐silane n‐octyldimethylchlorosilane (n‐ODMCS). The chloro functionality of organo‐silane modifiers was utilized to functionalize wood fiber. The resulting modified fiber was characterized for thermal stability (thermal gravimetric analysis), presence of organic groups on the surface (Fourier‐transform IR), for particle size (microscopy) and for its hydrophobicity by dispersing in toluene. The modified fiber was used for in situ polymerization of propylene to obtain a wood fiber–polypropylene hybrid. The terminal olefin functionality of 7‐ODMCS was utilized for co‐polymerization of propylene during in situ polymerization. The wood fiber–polypropylene hybrid samples were characterized for thermal analysis. In order to confirm the co‐polymerization of propylene in 7‐ODMCS modified fiber during in situ polymerization, n‐ODMCS modified fiber having no olefin functionality was also used in in situ polymerization. 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.
