I would like to fabricate porous PPSU based polymer membranes
Dear NdlovU,
Poly(vinylpyrolidone), Ethylene Glycol, Porpylene Glycol, Poly(ethylene glycol) etc. are goog porogens.
I think this answer might be helpful for you to prepare the membrane with different porosity.
Regards,
Sanjay
in addition to what dear chaudhri told before, I think you can use salts like NaCl and finnaly wash them with water.
