| Outline of Final Research Achievements |
Porous inorganic membranes have advantages of high temperature resistance, chemical stability and mechanical strength, therefore, various researches for water treatment have been investigated. In this study, stacked nanosheet membranes utilizing two-dimensional nanosheets were fabricated for the development of functional inorganic membranes with superior water permeability, separation performance as well as high antifouling property. We have successfully fabricated the stacked nanosheet membranes with high structural stability using simple vacuum filtration method. The nanosheet membranes show high rejection against anionic organic dyes and divalent salts, which were found to act as nanofiltration. Furthermore, the fouling resistance with recovery function of water flux under ultraviolet light irradiation was also confirmed.
