Abstract
Disclosed are a membrane structure including a carbon nanomaterial and NASICON-series ceramic particles, wherein an aqueous solution can pass through an electrode and a method of fabricating the same. There is disclosed a membrane structure of a flat membrane or hollow fiber membrane form, wherein the carbon nanomaterials are intertwisted to form a three-dimensional mesh-shaped structure and the NASICON-series ceramic particles material is combined with the three-dimensional mesh-shaped structure as a complex.
Claims9
A method of fabricating a membrane structure, comprising steps of:
- a) fabricating NA super ionic conductor (NASICON)-series ceramic particles;
- and
- b) forming a membrane structure of a flat membrane or hollow fiber membrane form in which the NASICON-series ceramic particles and a carbon nanomaterial have been intertwisted, wherein the membrane structure functions as a positive ion adsorption electrode for an electrochemical deionization process and a separation film for a membrane filtering process in a water treatment process.
