Graphene oxide based membranes with application in water treatment process

In recent years, graphene oxide has become one of the most attractive materials for design and manufacturing of membranes used in water treatment processes. Because graphene oxide shows unique properties, such as a high surface area, good mechanical properties, simple synthesis techniques, presence of various functional groups on its surface and the possibility of surface modification. Various methods have been proposed for preparing graphene oxide membranes, each of which has its own advantages and disadvantages. On the other hand, it is possible to control and adjust the functions and performance of these separation membranes by making changes in the synthesis process or by modifying graphene oxide itself. Here, Firstly, the various common methods for preparing separation membranes based on graphene oxide will be discussed. Then, methods of controlling and adjusting the performance of these membranes to attain more favorable conditions for water treatment processes will be developed.
