Permeability of oxygen through polymers. II. The effect of humidity and film thickness on the permeation and diffusion coefficients

Abstract

Abstract The values of the permeability coefficient P (cm 2 /sec) and the diffusion coefficient D (cm 2 /sec), of oxygen in some water‐soluble polymers at various values of relative humidity were determined. The amount of oxygen initially present in the polymer membranes was calculated. The effect of sample preparation and the film thickness on the transport parameters was investigated. The results confirm the possible effect of thickness on the rate of transport of oxygen in water‐soluble polymers.
