Water Transport in Polymer Coatings and the Correlation Between Coating Properties and Water Uptake in Aqueous Solutions at Elevated Temperatures
Bibliographic record
Abstract
The effect of water sorption on the properties of two polymer coatings for pipelines was studied. Water transport in both coatings during the early stages of diffusion followed Fickian behavior but showed non-Fickian behavior during long immersion times with a decrease in the water diffusivities. The increase in the coating capacitance correlated well with the amount of water absorbed in the coatings. The coating impedance during long-term immersion tests decreased exponentially with increased water saturation fraction of the coating and with increased solution temperature. The glass transition temperature of wet coatings was strongly dependent on the temperature of the soaking solution and the immersion time. The effect of the glass transition on the impedance, capacitance, and break point frequency of these coatings during immersion tests was not significant.

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.
