Similar variations can be seen in the ratio of [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII], indicating the role of variation of the chemical structure on the solubility coefficient, which also reflects the ability of the gas molecules to interact with the polymer matrix.
When faced with a non-Fickian situation, the effective diffusion and solubility coefficients can still be determined and are defined at steady state or equilibrium.
The corresponding experiments showed that the solubility coefficients of both phases were close to each other, and for the whole range of the inlet ozone concentration in gas the coefficients were 0.
B] is the solubility selectivity (the ratio of the solubility coefficients of Gases A and B).
At glassy polymer of PES in comparison with rubbery polymer of PDMS, penetrant diffusion coefficient is more important than solubility coefficient.

a] is the solubility coefficient of the purely amorphous material and [alpha] is the amorphous fraction.
From the two relationships we estimate the He solubility coefficient in PEANi to be about 7.
Equation 3 can be solved using the Newton-Raphson technique, and it shows that the equilibrium bubble size depends neither on the hydrodynamic nor the diffusional aspects of the bubble growth process, but rather on the initial conditions, temperature, final pressure, surface tension, gas molecular weight, and solubility coefficient.
2], and/or varying the solubility coefficient ratio of ([S.
In fact, permeability (P) can be defined as [Mathematical Expression Omitted] where [Mathematical Expression Omitted] is an average diffusion coefficient, while [Mathematical Expression Omitted] is an average solubility coefficient.
On the other hand, the diffusion coefficients of gases in membranes often change less than the solubility coefficients.
