Membrane distillation, as a growing membrane technology, has gained worldwide attention over the past few decades. It is possible to desalinate seawater by using membrane distillation process. In this project, reduced graphene oxide was synthesized by a green chemical method. Then, the structure and properties of the synthesized reduced graphene oxide was evaluated by performing FTIR and FESEM analyzes. Next, the synthesized reduced graphene oxide was coated on the polyvinylidene fluoride membrane by vacuum filtration method. Then, structural and functional evaluation of the fabricated composite membrane was performed in vacuum membrane distillation process. The optimized composite membrane reached 99.99% of salt rejection and 11.8 LMH of flux.
