Abstract
|
|
|
|
The oxygen permeation characteristics of BOPP, OPP and CPP membranes were studied against various thicknesses and temperatures. The experimental results showed that the present method of using electrochemical oxygen sensor was a convenient method for measurement of membrane permeability of oxygen and its activation energy, while the thickness dependency on permeability has an order of BOPP ＞ CPP ＞ OPP. And the activation energy of oxygen permeability showed different values for each membrane ranging from 13.1 kJ/mol to 28.5 kJ/mol, without depending on membrane thickness, presumably due to its depending upon membrane material itself.
