Directional permeability of asymmetrically oxidized poly(L‐methionine) film to oxygen dissolved in water

摘要

AbstractThe permeability of an asymmetrically oxidized poly(L‐methionine) film to oxygen dissolved in water was examined. It was recognized that the permeability along an increasing gradient of oxidized methionine composition is higher than the gradient is reversed. A qualitative analysis of this result was presented in terms of the oxygen solubilities into the film and water absorbed in the fil
