Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Introducing MOFs into the polymer matrix reduces methanol permeability relative to pristine SPPO and Nafion-115.
Caveat: No uncertainty or replicate statistics are reported.
p009 · 3.8 Methanol permeability · Linked to 3 structured results
The Fe-MIL-101-NH2 framework remains crystalline after solvent exposure, NAPI elution and incorporation into the membrane.
Caveat: Membrane PXRD peaks decrease because MOFs are wrapped in polymer, limiting phase-assignment sensitivity.
p005 · 3.2 Powder-XRD · Fig. 4 · Linked to 3 structured results
Fe-MIL-101-NH2 pore dimensions are large enough to host NAPI, enabling NAPI adsorption into the framework.
Caveat: Pore dimensions are partly from literature/simulation discussion rather than newly refined crystallography.
p004 · 3.1 Synthetic analysis · Fig. 1/Fig. 2 · Linked to 5 structured results
Hinsberg/sulfonamide chemistry connects MOFs or NAPI amines with PPO-SO2Cl, reducing phase separation in the composite membrane.
Caveat: IR/NMR support bond formation, but no quantitative grafting degree is reported.
p004 · 3.1 Synthetic analysis · Fig. 3 · Linked to 4 structured results
Proton conduction is proposed to arise from simultaneous Grotthuss-type structure diffusion and vehicle-type diffusion by mobile protonated NAPI.
Caveat: Mechanistic assignment is interpretive and supported by trends and schematic reasoning rather than direct isotope or activation-energy proof.
p009 · 3.7 Proton conductivity and mechanism · Fig. 12/Scheme 2 · Linked to 2 structured results
Encapsulated NAPI in MOFs is the main reason for enhanced high-temperature proton conductivity in the membrane.
Caveat: The ratio-series conductivities are visually estimated from Fig. 11 except the endpoint text value for the 6% encapsulated-MOF membrane.
