Preparation and Characterization of PPO Membranes Using ۱,۲-Dichloroethane Solvent: the Effect of Various Compositions on ContactAngle and Morphology

A membrane is a thin layer capable of selectively separating the components of mixtures.Polyphenylene oxide (PPO) is a popular material for film production due to its high glass transitiontemperature and low water absorptivity. NIPS is a commonly used technology for preparingpolymeric membranes because of its adaptability. In this study, the effect of the composition ratiobetween PPO and the solvent ۱,۲-dichloroethane on the contact angle and morphology of membranesprepared by the NIPS method is investigated. According to result obtained, with an increase in thepolymer weight percentage, the contact angle increases. The ۱۴M membrane (۱۴wt.% PPO, ۸۶wt.%solvent), is considered a more hydrophilic membrane with a contact angle of ۷۲.۸۷۴°. Cross-sectionalSEM images shows a uniform, symmetric sponge-like structure throughout the thickness
