Abstract
Ultrahigh-molecular-weight polyethylene (UHMWPE) fibers are valued for their high strength-to-weight ratio and are employed in a wide variety of commercial applications. However, because of its low surface energy, UHMWPE can fail in certain applications such as fiber-reinforced composites. This is due to its poor interfacial adhesion with polar matrices, making it challenging to incorporate into composites or retain polar dyes or colorants. Herein, we describe the use of polyamine primers for coating UHMWPE weaves, covalently bonding the aliphatic chains through C–H insertion, leading to strong covalent interactions between the fabric and polyamines. We further demonstrate that the polyamine-coated UHMWPE surfaces can successfully react with epoxy resin through nucleophilic addition reactions to enable the production of epoxy composites. Furthermore, we show the use of polyamine-coated UHMWPE in secondary functionalization with amine-reactive compounds, such as dyes, through covalent linkages that result in very strong color fastness.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
