N owadays, with population growth, the demand for fresh water is rising rapidly.
Development of membrane based systems such as reverse osmosis, nanofilteration,
ultrafilteration, and microfilteration is important strategy to reduce water scarcity.
Improving performance, life time and other properties of membranes are always important
issues to reduce cost and energy consumption of membrane based-water treatment system
and should be considered to develop membrane technologies. Recently, graphene oxide
has attracted great attention to modify relevant membranes and manufacture novel
nanocomposite membranes. Graphene oxide has unique structure and properties and can be
produce at commercial scale with low cost. Functional groups of graphene oxide including
hydroxyl, epoxy and carboxyl lead to strong interaction with polymeric matrix. Using
graphene oxide in surface and matrix of polymer can improve mechanical strength, thermal
stability, hydrophilicity and antifouling of polymeric membrane and subsequently improve
membrane flux and performance in desalination process. In this review, the processes for
modifying of membrane surface and synthesizing of nanocomposite membrane using
graphene oxide have been evaluated. The mechanism of graphene oxide influence on
membrane porosity, structure, characteristics and performance has been also discussed.
