An Investigation Into Surface Modificatin Of Polyethylene Film By Ozonation
Bibliographic record
Abstract
<p>The aim of this study was to investigate the hydrophilic modifications of the polymer films by ozonation. In this study, the polymer films (LD+LLDPE) were ozonated in gas phase and in aqueous phase, respectively. The surfaces of the polymer films were investigated in terms of peroxide generation, contact angle measurement, Fourier transform infrared (FTIR) spectroscopy and tensile strength measurements. </p> <p>Experimental results indicated that the amount of peroxide groups generated increased with ozonation time and applied ozone dose. It was also observed that the efficiency of ozonation was similar for gas phase ozonation, and aqueous ozonation. Catalyst screening revealed that Fe (III) and Cu (II) were both effective in accelerating peroxide generation. </p> <p>The hydrophilicity improvement of the film after ozonation was confirmed by contact angle measurements and Fourier transform infrared measurements. The LD+LLDPE films kept good tensile strength after ozonation. Even after 120 min ozonation at 1.0 wt% applied ozone dose, 85% of the tensile strength still remained. </p> <p>The application of catalyst to modify polymer film is the first of its kind. In this study, the approach proved to be successful for LD+LLDPE films.</p>

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.
