| Abstract Scope |
Functionalized organo–mineral composite membranes composed of polyacrylonitrile (PAN) and magnetite (Fe₃O₄) nanoparticles were fabricated via the phase inversion process. Dimethylformamide (DMF) was used as the solvent and poly(vinylpyrrolidone) (PVP) as the pore-forming additive. The dope solutions were mechanically stirred at 300 rpm for over 8 h and cast at 10 mm/s with pre-evaporation times of 10–20 s, producing ultrafiltration membranes with thicknesses of 100–200 μm. Scanning electron microscopy was employed to examine nanoparticle alignment, membrane morphology, pore size distribution, and nanofiller dispersion under varying casting parameters and magnetic fields. The results show that membrane porosity increases with pre-evaporation time, while hydrophilicity improves with increasing Fe₃O₄ content. However, permeability decreases when nanoparticle loading exceeds 3 wt% due to agglomeration and pore blockage. Overall, both casting conditions and nanofiller concentration significantly influence membrane water adsorption and retention properties. |
