Condensation polymer membrane chemistry: BASFRecent Research Landscape

Standard membrane casting solvents like NMP face increasing regulatory pressure and toxicity risks, which this specific pyrrolidone derivative mitigates. Controlling the polymer-solvent interaction during phase inversion ensures consistent pore morphology and hydrophilicity in polyphenylene sulfone filters.

What technical problems is BASF addressing in Condensation polymer membrane chemistry?

Inadequate viral filtration efficiency

(16)evidences

Inherent hydrophobicity in polyarylsulfone structures leads to rapid protein adsorption and pore clogging. Reducing this affinity prevents flux decline and extends operational lifespan.

Membrane chemical degradation

(3)evidences

Chemical instability and loss of structural integrity due to reactive species. Preventing material breakdown ensures operational longevity in harsh filtration environments.
