Abstract
Model fluorous−ionic copolymer systems were synthesized and studied to investigate the role of polymer architecture on morphology and properties of solid polymer electrolytes. Two types of compositionally similar but architecturally distinct copolymers were investigated: P(VDF- co -CTFE)- g - S PS graft copolymers, comprising a hydrophobic fluorous backbone and sulfonated styrene side chains, and P(VDF- co -HFP)- b - S PS diblock copolymers, comprising a hydrophobic fluorous segment linearly connected to a sulfonated styrenic segment. The macromolecular structure plays an important role in determining membrane morphology. Graft membranes possess a small ionic cluster morphology while diblock membranes possess a lamellar-like morphology. These morphological differences affect the threshold of ionic percolation, water sorption, proton mobility and concentration, proton conductivity, and anisotropy of ion conduction.

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 it
