Water diffusion

The sorption and diffusion properties of water vapor in a new, short-side-chain perfluorosulfonic acid ionomer (PFSI) membrane have been investigated at different temperatures in the range of 35÷120°C. Experiments show that pretreatment of the membranes under vacuum at low temperatures leaves in the

The paper is devoted to the description of specific differences of water transport between petroleum-based (‘petro’ polymers) and environmentally friendly polymers (‘green’ polymers). The differences in water transport mechanisms are presented for poly-R-(3-hydroxybutyrate) and its blends with low d
