Crosslinked SPEEK membranes: Mechanical, thermal, and hydrothermal properties [PDF]
The thermal and mechanical behavior, the water uptake (WU), and water diffusion coefficient of sulfonated poly(ether ether ketone) (SPEEK)membranes annealed at 180 degrees C for different times were explored by high-resolution thermogravimetric analysis,

Resin content calculation of carbon fiber/poly (ether ether ketone) by thermogravimetric analysis
Resin content of composites is a dominant factor of macroscopic properties and essential to study. Taking carbon fiber/poly (ether ether ketone) (CF/PEEK) composites molded by various means as examples, a method for resin content calculation obtained ...

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