Abstract

The availability of freshwater resources is dwindling in many parts of the world, a problem that is anticipated to grow with budding population. One promising source of potable water is the world's virtually limitless supply of seawater, but so far desalination technologies have been too expensive for widespread use. With current advances in nanotechnology and the development of diverse nanomaterials, which can be employed for successful membrane fabrication, nanostructured membrane-based desalination might be ready for the next generation of breakthroughs. Typically, by facilitating the manipulation of matter and control of transport at nanometer length scales, fabrication of nanostructured membranes offers new opportunities to advance water desalination technologies. This chapter will provide a broad discussion on highly promising nanomaterials; their specific morphology, which leads to specific enhanced water permeation, membrane-vapor interactions, their membrane fabrication procedures, and potential applications in leading desalination technologies.
