WebIt was concluded that the most influential parameter for the permeation is the diffusion coefficient of the gases. The permeability and selectivity decrease as the operating pressure and PEG content are increased. Furthermore, the results showed that the addition of 5 wt% of PEG into PC increases the CO2/CH4 selectivity from 26.6 +/- 0.99 to 40 ... WebPermeation analysis. We measure the barrier effects of polymers and coatings to the permeation of gases and volatile substances. Fraunhofer IVV developed a method that would allow the barrier properties of polymerfilms to be measured during the actual production process. In this way the permeation measurement of films can be speeded up ...
