Hydrophobic networks for advanced proton conducting membrane: Synthesis, transport properties and chemical stability

Influence of different alkyl‐methylimidazolium tetrafluoroborate ionic liquids on the structure of pebax® films. Consequences on thermal, mechanical, and water sorption and diffusion properties

“…The antiplasticization phenomenon observed at water activity above 0.3 was more deeply analyzed using the following equation: where D agg is the limit diffusion aggregation coefficient at nil concentration, β is the antiplasticization coefficient and M is the water uptake in the material. The antiplasticization coefficient β was determined for each film from the linear regression of the decreasing part of the curve ln( D )=f( M ).…”

3D Mass diffusion in ordered nanocomposite systems: Finite element simulation and phenomenological modeling

“…Problems involving gas diffusion arise today in a large range of fields such as food preservation, medicinal products packaging, solar cell protective coatings, fuel cell membranes, fuel and gas transportation, as a few. Most of these domains need materials that combine low cost, easy processing, long‐term flexibility, and barrier properties.…”

Diffusion mechanism of byproducts resulting from the peroxide crosslinking of polyethylene

“…Moreover, polymer–species affinity can also play an important role in the diffusion rate. Indeed, when the interactions are higher, the diffusion rate is usually lower . In the next step, we tried to determine whether the molar volume was the governing parameter of diffusion in our system.…”
