Hydrogen permeability of polymers
Web5 jan. 2024 · The permeability of fillers, such as silica or many types of carbon materials, is lower than that of polymeric materials. To investigate the permeability of a polymer that contains a low permeable filler, Fig. 1 (a) shows that the penetrant gas molecules bypass the filler and traverse the polymer film. The length of the apparent transfer pathway, … WebThe permeability, solubility and diffusivity can be very different for different polymer-permeant systems and depends on many factors like chemical composition, degree …

WebMembranes with high hydrogen permeability and good selectivity for the gas pairs H2/CH4 and H2/N2 were obtained. For H2/CO2, selectivity almost vanished after thermal rearrangement. In all cases, their hydrogen permeability increased with increasing loads of PPN until around 30% PPN with ulterior fairly abrupt decreasing of permeability for all … Web15 mrt. 2024 · @article{Prewitz2024PolymerCG, title={Polymer coated glass capillaries and structures for high-pressure hydrogen storage: Permeability and hydrogen tightness}, author={Marc Prewitz and M.
