“…Relative to pristine PVDF membranes, the BSA rejection rates of GO/PVDF, CS/PVDF, and CS‐GO/PVDF increased by 12.22, 10.17, and 17.72 %, respectively. The rejection rate of GO/PVDF was higher than that of CS/PVDF, which could be explained by the complete absorptive action caused by adding GO nanomaterials , . The GO sheets aggregate due to π‐π conjugate interactions .…”

Chitosan-functionalized graphene oxide (CS-GO) was synthesized and incorporated into a poly(vinylidene fluoride) (PVDF) ultrafiltration membrane. The effect of CS-GO addition on the morphology and membrane performance was studied through water contact angle, scanning electron microscopy, atomic force microscopy, porosity, pore size, and permeation measurements as well as rejection tests and antifouling experiments. The CS-GO/PVDF membrane exhibited higher water flux, bovine serum albumin (BSA) rejection rate, and water flux recovery ratio, and lower BSA solution flux attenuation rate than those of unfilled PVDF, CS/PVDF, and GO/PVDF membranes. The excellent water permeability and antifouling performance can be attributed to the high hydrophilicity and good dispersion of CS-GO in the matrix.

“…Those limitations can be eliminated through the use of additives that increase the hydrophilicity. The introduction of oxide nanoparticles, such as TiO 2 , Al 2 O 3 , Fe 3 O 4 , or SiO 2 , and carbon nanotubes into the polymer matrix subsequently improves the hydrophilic properties of the membrane, and it also has a positive influence on its strength and permeability . In recent years, investigations have revealed that similar effects could be expected after graphene oxide (GO) was introduced into the polymer matrix .…”

In this article, we present our study of the influence of a graphene oxide (GO) additive and the method of preparation on the properties of membranes. Poly(vinylidene fluoride) (PVDF)/GO membranes were obtained by an inverse phase method, which was conducted by two different methods. The first one was based on solvent evaporation, and the second method was a coagulation bath in distilled water. Our studies clearly showed that the introduction of the GO nanoadditive into the polymer membrane matrix played a major role in the pore process formation, and it also contributed to the reduction of the contact angle, and this led to an improvement in the hydrophilic properties of the obtained membranes. Furthermore, the PVDF/GO membrane preparation process had a direct influence on the thickness and porosity. Both of these factors had a direct influence on the transport properties of the membrane.
