Naphthalene‐containing poly(arylene ether ketone) with low dielectric constant
Bibliographic record
Abstract
ABSTRACT A low dielectric constant poly(arylene ether ketone) containing naphthalene and trifluoromethyl groups (FPNAEK) were prepared and characterized. The FPNAEK showed excellent thermal stability (Td5 = 443 °C ) and low water absorption. The dielectric constant decreased significantly after introducing trifluoromethyl group, in comparision with poly(arylene ether ketone) containing naphthalene (PNAEK). The dielectric constant of FPNAEK is about 2.5 between 1 kHz and 1 MHz at room temperature, which is much lower than that of commercial poly(ether ether ketone) (3.3) and PNAEK (2.78). © 2018 Wiley Periodicals, Inc.

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.
