UV-Absorbing Cellulose Nanocrystals as Functional Reinforcing Fillers in Poly(vinyl chloride) Films
Bibliographic record
Abstract
Ultraviolet (UV)-responsive poly(cinnamoyloxy ethyl methacrylate) (PCEM) was grafted on cellulose nanocrystals (CNCs) via the surface-initiated atom transfer radical polymerization technique. The resultant PCEM-grafted CNCs (PCEM- g -CNCs) exhibit high UV absorption properties and undergo cross-linking when subjected to UV radiation. When the PCEM- g -CNC nanohybrids were incorporated into poly(vinyl chloride) (PVC) matrix, transparent nanocomposite films with UV-blocking characteristics were obtained. Comparison of the optical and mechanical properties of the films before and after UV irradiation confirmed that the PCEM- g -CNCs are excellent thermal and UV stabilizers for PVC. In addition, the tensile properties of the PVC film were increased significantly and further enhanced after UV irradiation.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
