The effects of water on the morphology and the swelling behavior of sulfonated poly(ether ether ketone) films [PDF]

open access: yes, 2015
Thin sulfonated poly(ether ether ketone) films swell excessively in water. The extent of water-induced swelling is shown to be correlated with the optical anisotropy of the films, due to two distinct phenomena. Firstly, the optical anisotropy is directly
