      One of the grand challenges afflicting human society is inadequate access to suitable water resources.  Membrane water treatment is expected to play an increasingly important role in addressing the water challenge.  In this presentation, I plan to discuss the development of polymer-matrix nanocomposite membranes for drinking water treatment, brackish and seawater desalination, and wastewater treatment and reuse. The advanced nanocomposite membranes could be designed to meet specific water treatment applications by tuning their structure and physicochemical properties (e.g. hydrophilicity, porosity, charge density, and thermal and mechanical stability) and introducing unique functionalities (e.g. antibacterial, photocatalytic or adsorptive capabilities).  Based on the membrane structure and location of nanomaterials,  nanocomposite membranes could be classified into (1) conventional nanocomposite, (2) thin-film nanocomposite (TFN), (3) thin-film composite (TFC) with nanocomposite substrate, and (4) surface located nanocomposite.  Examples will be presented to illustrate how materials properties could be explored to enhance membrane performance and antifouling characteristics. Challenges and future research directions in developing high performance nanocomposite membranes will also be discussed.
