Porous poly(lactic acid) and PLA‐nanocomposite structures
Bibliographic record
Abstract
Abstract This article presents foaming behaviors and cellular structures of poly(lactic acid) (PLA)‐clay nanocomposite and respective neat PLA foams using CO 2 as a foaming agent. The effects of nanoclay and foaming conditions on the foam morphology and mechanical properties of neat (PLA) and PLA‐clay nanocomposites have been investigated by temperature modulated differential scanning calorimeter (TMDSC), X‐ray diffraction, scanning electron microscopy, and tensile properties. CO 2 ‐induced crystallization in PLA and PLA‐clay nanocomposites and the crystallinity increased with an increase in saturation time. The present of clay acted as nucleation site to facilitate the crystallization process of PLA thus resulted in smaller crystallites and lower crystallinity. Unique skin‐core foam morphologies in PLA and PLA‐clay nanocomposites were obtained by controlling the crystallinity. Clay nanoparticles served as nucleation sites to generate foam morphology in PLA‐clay sample with high crystallinity. The introduction of the cellular structure improved the mechanical strength of the material and the specific strength of PLA foams were increased in the presence of a small amount of MMT. © 2011 Wiley Periodicals, Inc.

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; a candidate call from one teacher head, not a consensus.
