Structural effects on the nano-scale morphology and conductivity of ionomer blends
Bibliographic record
Abstract
The role of graft and diblock ionomer architecture on the morphology and properties of ionomer/fluoropolymer blends is examined. The graft copolymer consists of a partially fluorinated backbone of P(VDF-co-CTFE) and partially sulfonated polystyrene (PS) side chains while the diblock copolymer consists of a block of P(VDF-co-HFP) and a partially sulfonated PS block. These ionomers are blended with fluoropolymers possessing a chain length that matches the average sequence length of the fluorous block segment of the ionomer. The results from this study are surprising: graft ionomers are primarily insensitive to blending due to the incorporation of the non-ionic fluorous polymers into the domains of the perfluorinated backbone which does not deleteriously affect the interconnecting proton conducting ionic clusters. In contrast, diblock ionomers are highly sensitive to the addition of fluoropolymers and despite the observation that ionic channels are retained, water sorption is decreased due to the increased volume of the non-ionic domains, which decreases proton mobility and proton conductivity.

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.
