▎ 摘　　要

In this paper, novel flat sheet membranes were prepared via the vapor induced phase separation method and using the poly(propylene fumarate)/(graphene oxide/Pluronic F-68)/2-pyrrolidone casting solutions. The membrane properties such as morphology, mechanical, hydrophilicity and permeation properties were examined as functions of GO/Pluronic F-68 additive concentration and exposure vapor time. These membranes were characterized by scanning electron microscopy, Fourier-transform infrared spectroscopy, mechanical testing, molecular weight cut-off evaluation, contact angle measurement and dynamic wetting tests. The experimental results indicated that modified membranes exhibit significant differences in surface properties and inherent properties. Also, exposure time has an effective role in membrane structure. So that by increasing the exposure time up to 20 min, the structure of the membrane changed from an asymmetrical structure to a symmetrical structure with the cellular structure. In addition, an increase in mechanical proper-ties and resistance of membranes was observed for the poly propylene fumarate membranes mod-ified with GO/Pluronic F-68 and exposed to vapor for 20 min. These membranes have a relatively noticeable rejection of the local ceramic factory wastewater pollutants of properly than others.
