Abdelkader BOUAZIZ Popular answer

Dear Koceila Maouacine, for what it stands this abreviation SPPSU? Is it polysulfone (PSU)? My Regards

Abdelkader BOUAZIZ

Or you mean sulfonated polyphenylsulfone (sPPSU) membrane?

Koceila Maouacine

Dear Abdelkader, thank you for your answer, SPPSU is the sulfonated

poly(phenyl sulfone).

YES sulfonated polyphenylsulfone (sPPSU) membrane

Most of the work is done on PSU. Membranes of sPPSU are made by other techniques or prepared by chemical post-modification of PSU. The following document may be helpfull since it mention the electrospinning of sPPSU. My Regards
