In the past four years, the PI of this proposal has focused on the advancement of ceramic nanotubes. Based on what our group has developed, this project will continue the investigations of the fundamentals of ceramic nanotubes as well as their device applications. We propose a two-phase research plan to achieve our goals. In Phase I, we will employ the techniques of interior functionalization and molecular simulations for the assessment of the nanotube properties of water and ion transport. Through the investigation of Phase I, we will identify several promising types of ceramic nanotubes for fresh water production. In the study of Phase II, we will employ the ultrasonic nozzle spray deposition for the fabrication of ultrathin nanotube membranes for the tests of sea water desalination. At the sample time, a number of membrane characterization will be conducted, including SEM, AFM, GISAXS, and GIWAXS. We will precisely control the microstructure of ceramic nanotube membranes for the optimization of their fresh water production performance. The ultimate goal of this proposed research is to fabricate novel ceramic nanotube membrane for the high-flux freshwater production.陶瓷奈米管水處理奈米管薄膜超音波噴塗ceramic nanotubewater treatmentnanotube membraneultrasonic nozzle spray deposition.
