It can be used in different processes, such as membrane filtration and gas separation while also playing key roles in membrane contactor and membrane reactor. Functional inorganic membranes could be the only solution to many challenging separation applications at high temperature or harsh chemical environments. 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. Many experts have concentrated on this field to find other fabrication methods of inorganic membrane. In the past three years, we focused on developing new fabricating method and proposed a three-year term project to successfully develop a promising, low energy consumption and cost effective atmospheric plasma spray (APS) technique for fabricating porous ceramic membranes. In the coming three years, we will focus on materials design from the previous focus of developing fabrication method. We introduce a new concept of geomimetic approach to design novel inorganic membranes. Several potential routes intentionally mimic existing geophysical/geochemical processes will be proposed to design functional inorganic membranes from a fundamental understanding of formation mechanism and morphology of natural inorganic materials using a geomimetic approach. This sequential project proposes a three year term. In the first year, the focus is on the development of super-hydrophobic functionalized porous inorganic membrane using APS for membrane contact applications on energy issue. In the second year, we will utilize both of hydrothermal synthesis and APS methods for fabricating visible-light photocatalytic functionalized inorganic membranes for wastewater treatment applications. In the last year, we will extend the APS technique to bio-applications with fabricating functionalized hydroxyapatites to increase its biocompatibility and bond strength.仿地質薄膜大氣電漿噴塗分子動態模擬薄膜表面改質Geomimetic MembraneAtmospheric Plasma SprayMolecular Dynamic SimulationsSurface Modification
