Abstract

The morphological studies of poly(styrene)–poly(ethylene glycol)–chlorobenzene films have been performed using scanning electron microscopy. The average diameter of the holes present in the coatings decreased from 7.68 to 3.74 µm with the increase in the polymer content from 5 to 10%. The solvent played a major role in forming ordered porous polymer films. Asymmetric membrane formed at different concentrations of the ternary system. The effects of various parameters like polymer mass fraction, initial film thickness, and technique of application, on the pore size and uniformity have been studied. The membranes are formed at different concentrations of the ternary system.
