Abstract
⸠We measure non-Fickian organic solvent (VOC) sorption in glassy polyimides. ⸠These polyimides (P84, Matrimid) are important Nanofiltration membrane materials. ⸠VOC-sorption speeds are found to be different in both important polyimides. ⸠Non-Fickian VOC-sorption is modeled using a Maxwell-Stefan diffusion model. ⸠Diffusion coefficients are fitted to experimental data of the polyimide/VOC systems.
