Abstract

fetched live from OpenAlex

The preparation and characterization of hybrid nanocomposites based on polypropylene (PP) with Moroccan montmorillonite (MMT)/graphene nanosheets (GNs) is reported in this article. In particular, hybrid nanocomposites were prepared by melt compounding for different MMT:GNs ratio for a total loading of 3 wt%. From the samples produced, nanofiller dispersion in the polymer was monitored by scanning electron microscopy and Fourier transform infrared spectroscopy was used to better understand the interactions between both nanofillers and the matrix. Then, tensile and torsion tests were performed to characterize the nanocomposites in the solid state, while rheological properties were obtained in the melt state to better understand the complete behavior of these hybrid nanocomposites. The results show that GNs is more effective than MMT at modifying the properties of these nanocomposites, but taking everything into account, a 50/50MMT/GNs ratio is optimum which represents a good balance between strength, ductility, and rigidity under the conditions tested.

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.
