Subject: copolymer for O2 membrane

I am looking for a copolymer which is both amorphous and crystalline so as to be permeable to O2, but not too permeable that it is completely flow dependent. I am testing materials which could be used for dissolved oxygen membranes and I am looking for a polymer with lower flow dependence than teflon. The membrane must be submerged in water to record a DO reading, and I am having difficulty with low turbidity leading to a false reading due to the oxygen in the water being reduced so quickly that it cannot be replaced in non-turbid water, so the DO appears to be lower than it is. Any help is appreciated.
