The primary objective of this proposal is to develop and apply a two-dimensional (2D) MoS2 layers-integrated hygroscopic nanofilm from the concept of biomimicry for improved solar evaporation and desalination technology. The integration of the 2D MoS2 layer-based solar evaporator allows for target object specifications to be met at a low-cost with the advantages of photo-thermal material stability and longevity of the technology. This newly fabricated MoS2-PU sponge will provide benefit to American coastal cities by providing a source of water utilizing two abundant renewable resources.

The team consists of those in the Department of Civil, Environmental, and Construction Engineering: Dr. Woo Hyoung Lee (PI), Dr. Jae-Hoon Hwang (co-PI), Stephanie Stoll (student team leader), and Amaya Watson-Bajorek. In the Department of Materials Science and Engineering: Dr. Yeonwoong Jung (co-PI), Dr. Changhyeon Yoo, Brandon Osorto, and Sang Sub Han.

A global increase in water scarcity due to an exponentially growing population and the overutilization of freshwater resources has raised questions regarding the sustainability of fresh water supplies. There is more than enough available saltwater on earth to compensate for the freshwater scarcity, however, current desalination technologies are physically and economically limited. The primary objective of this proposal is to develop and apply a two-dimensional (2D) MoS2 layers-integrated hygroscopic nanofilm from the concept of biomimicry for improved solar evaporation and desalination technology. The integration of the 2D MoS2 layer-based solar evaporator allows for target object specifications to be met at a low-cost with the advantages of photo-thermal material stability and longevity of the technology. This newly fabricated MoS2-PU sponge will provide benefit to American coastal cities by providing a source of water utilizing two abundant renewable resources.
