Effects of Starch Content and Compatibilizer on the Mechanical, Water Absorption and Biodegradable Properties of Potato Starch filled Polypropylene Blends
Bibliographic record
Abstract
Tensile, water absorption and biodegradable properties of potato starch filled polypropylene blends have been investigated. Polypropylene grafted maleic anhydride (PP-g-MA) was used as compatibilizer. It was observed that the tensile strength and elongation at break are inversely related to the starch content but Young's modulus followed a direct relationship with the starch content. However, the addition of PP-g-MA to the blends improved the tensile strength and elongation at break even though they were still lower than the neat polymer but the Young's modulus increased progressively. This is as a result of the enhanced interfacial bonding between the starch and matrix which can be proved by the SEM images. The tensile strength and elongation at break of the compatibilized blends increased by 30.59%; 42.62% and 23.36%; 24.62% in comparison with the uncompatibilized blends at 10 wt.% and 50 wt.% respectively. The percent water absorbed and weight loss of the PS/PP were higher than the CPS/PP blends due to poor interfacial bonding. Biodegradation products of the blends showed no deleterious effects on the growth of plants.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
