Abstract

fetched live from OpenAlex

Abstract Nanocomposite films performance parameters, including barrier and properties for packaging films, can be affected by variables such as the type and concentration of nanoparticles. In this investigation, Polyvinyl alcohol (PVA) nanocomposite films were prepared by solution casting method with different combinations of Montmorillonite (MMT) platelets and Titanium Oxide (TiO 2 ) spherical nanoparticles.A support vector machine (SVM) was implemented to study the thin nanocomposite films' behavior to changes in the independent variables. The SVM model predicted oxygen transmission rate (OTR), water vapor permeability (WVP|), Young ̓s Modulus (YM), ΔE, opacity, tensile strength (TS), and elongation at the breakpoint (EB) with an error of less than 6.43%. A Genetic Algorithm (GA) was applied to find the optimal nanoparticle concentration to achieve optimum film performance. Therefore, the results exhibited that the optimum film performance depends on the type and concentration of nanoparticles. Results show that the optimum loading of nanoparticles in this research should be between 0.5-1 wt% for TiO 2 and 2.5–3.5 wt% for MMT.

Teacher imitation

Not 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.
