Crystalline swelling
WebRegardless of mixing temperature, the preservation of crystallites upon swelling is critical due to ionomer crosslinking provided by crystalline regions, which ensures membrane integrity even at very high solvent uptake (≈200% at a mixing temperature of 80 °C). The physicochemical properties of a swollen membrane have much in common with ...

The experimental techniques also were applied to the swelling properties of soil clays known to be high in montmorillonite. Results suggest that the poor crystallinity of soil montmorillonites is much more apparent at high water contents.
