some where with quick sending service... I need very little piece of this membrane to use a support
Do you think so? See the picture on the website: http://www.century2000.cz/produkty/prodej-polyesterovych-roun-a-netkanych-textilii/#dscn4172-jpg
If so, what big piece from this material you need?
adding graphene oxide / rGO / graphene have shown conflicting surface roughness changes in Polyethersulfone. for rGO in specific, why do we have roughness decrease whilst porosity has increased?
