It can be used in different processes,such as microfiltration, ultrafiltration and gas separation while also playing a key role in membrane reactor. Inorganic membranes could be the only solution to many challenging separation applications at high temperature or harsh chemical environments. Many experts have concentrated on this field to find other fabrication methods of inorganic membrane. The most common method is by sol-gel processing which creates small pores and has a narrow distribution but the complexity of process, time constraints and high manufacturing costs are the main barriers to market growth. As such, industrial applications are restricted by these factors. This project proposes a three year term. In the first year, the focus is on the development of a porous ceramic membrane. This utilizes an atmospheric plasma spray technique which is a simpler and more cost effective process. Nevertheless, the key points of controlling porosity in the coating layer are the behaviors of velocity and temperature of in-flight particles. In the second year, we will utilize Computational Fluid Dynamics to simulate this behavior and also reduce the cost of capital. In the last year, we will modify the hydrophilic surface of the inorganic membrane to extend the application.大氣電漿噴塗陶瓷薄膜計算流體力學薄膜表面改質Atmospheric Plasma SprayCeramic membraneComputational Fluid DynamicsSurface Modification
