But how exactly does it work?Photo: My fantastic GORE-TEX walking boots. They're leather on the outside, but the lining is made of completely waterproof GORE-TEX. You can jump in puddles all day long in a pair of these and your feet won't get wet....
NafionSupercritical carbon dioxideBound waterIonic poresLaplace pressureWe address the effect of exposure to sc CO2 on the properties of Nafion membranes. A simple model is proposed to describe the pressure-induced reorganization of the phase-separated matrix. The model predicts that the cylindrical ...
An ion-exchange material is typically modeled as a porous medium consisting of a fixed matrix with the pores filled up with water and additional mobile ions. This may sound completely wrong to anyone who has seen, for instance, a Nafion® membrane, one of the most common polymer electrolyte...
using wells installed in a sand tank, are generally not recommended because the sand tank walls will act as impermeable boundaries and will thus prevent the application of classical analytical models for pumping test interpretation. However, in 3D ...

This is usually Nafion, a polymer consisting of a polytetrafluoroethylene (PTFE) backbone, with perfluorinated-vinyl-polyether side chains terminating in sulfonic acid groups. The state of water and ion transport in this have been extensively studied by neutron techniques including INS [96], QENS ...
