Dielectric properties of epoxy/POSS composites
Bibliographic record
Abstract
In this work, the dielectric responses of epoxy/POSS composites with different contents of liquid Triglycidylisobutyl-POSS (TGIB-POSS) varying from 1wt% to 10wt% were investigated using Broadband Dielectric Spectroscopy (BDS) at 20°C, before and after exposure to a post heat-treatment of the samples. Besides the known β-peak in the vicinity of 105Hz, an additional interfacial loss peak for the epoxy/POSS composites with more than 1wt% TGIB-POSS has been observed for low frequencies. Furthermore, loss tangent values of the composites were found to be reduced after incorporation of POSS, along with an increased volume resistivity, especially after thermal ageing. Differential Scanning Calorimetry (DSC) has shown a decrease in glass transition temperatures with increasing TGIB-POSS content.

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.
