Abstract

Microporous membranes were obtained by dry-wet phase inversion from asolution of cel-lulose acetate (CA) in acetone (13, 14 and 15 wt%). Polyethylene glycol was used as ablowing agent. The structure and mechanical properties were examined. FT-IR spectra show that the addition of polyethyl-ene glycol improves the thermodynamics of the solution and increases the hydrophilicity of the mem-brane. The SEM method confirmed the microporous structure of membranes with an asymmetric struc-ture and various pore sizes and porosities. Higher CA concentration resulted in better tensile properties.Keywords: biopolymers, cellulose acetate, membrane, phase inversion
