Dynamic interfacial tension between a thermotropic liquid‐crystalline polymer and a flexible polymer
Bibliographic record
Abstract
Abstract When a short fiber of a thermotropic liquid‐crystalline polymer retracts in a quiescent, flexible polymer matrix, the polydomain texture inside the fiber evolves simultaneously. We have demonstrated experimentally that the two processes are coupled. The dynamic interfacial tension, determined from the retraction of the short fiber, decreases with time. On the other hand, we have determined the aspect ratio of the polydomains inside the fiber through the power spectra of two‐dimensional discrete Fourier transformations of polarized optical microscopy images. The polydomains are initially elongated and aligned with the fiber axis. As the fiber retracts into a spherical drop, the polydomains first retract into a circular shape and then are squeezed into elongated shapes perpendicular to the original fiber axis. An exponential function correlates the evolution of the dynamic interfacial tension with that of the aspect ratio of the textures. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 3114–3120, 2006

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.
