Considerations of Macromolecular Structure in the Design of Proton Conducting Polymer Membranes: Graft versus Diblock Polyelectrolytes

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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
