Abstract |
Polyaziridine or polyetyleneimine (PEI) was introduced as filler in cellulose acetate (CA) to fabricate mixed matrix membrane
(MMM) for hemodialysis. Diffusion-induced phase separation (DIPS) method was followed for making PEI/CA MMM membranes.
Effect of variation in the amount PEI was also examined on the morphology and performance of CA membrane. The
surface morphology of pure and MMM membranes was studied by SEM, AFM, contact angle, and FTIR. Results of all
characterization techniques revealed homogenous and significant blending of PEI content into pure CA matrix. Moreover,
performance efficiency of MMM membranes was investigated in terms of pure water flux (PWF), urea clearance, and bovine
serum albumin (BSA) rejection. The concomitant decrease of contact angle from 78° to 69° in PEI/CA MMM membranes of
varying composition successfully demonstrates enhancement in surface hydrophilicity of MMM membranes. For protein rejection,
all PEI/CAMMMmembranes rejected > 90% of BSA relative to
