Professor Matsuyama Hideto’s research group at Kobe University’s Research Center for Membrane and Film Technology<\/a> has successfully developed a new desalination membrane. They achieved this by laminating a two-dimensional carbon material on to the surface of a porous polymer membrane.<\/p>\n


\n <\/section>\n

Desalination membranes are used to produce freshwater from seawater. In order to solve the worldwide issue of insufficient freshwater resources, researchers are striving to develop desalination membranes that are not only permeated by water faster than those currently in use but also remove salt efficiently, so that more effective, low-energy desalination systems can be implemented.<\/p>\n

In this research study, graphene oxide nanosheets, which are a type of two-dimensional nanomaterial, were stacked upon the surface of a porous membrane after being given a chemical reduction treatment, enabling a desalination membrane layer of app<\/a>roximately 50 nanometers (nm) to be developed (a nanometer is 1\/20,000th of a millimeter). The developed membrane has the potential to perform highly efficient desalination because it is possible to control the gaps between its nanosheets and the charge on the nanosheets’ surfaces. It is hoped that this research will contribute towards the application and implementation of futuristic desalination membranes.<\/p>\n

These research results were published in Journal of Materials Chemistry A<\/i> on November 18, 2020.<\/p>\n
