Title:
CERAMIC NANOFIBER STRUCTURE, CERAMIC NANOFIBER SEPARATION MEMBRANE MODIFIED WITH PHOTOCATALYST, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2020/184863
Kind Code:
A2
Abstract:
Provided are: a highly flexible ceramic nanofiber structure; a ceramic nanofiber separation membrane having excellent photocatalytic efficiency; and a method for manufacturing same. A ceramic nanofiber structure according to an embodiment of the present invention includes a first ceramic component and a second ceramic component. A highly flexible ceramic nanofiber structure can be obtained by controlling the diameter of ceramic nanofibers to adjust the average pore size and maximum pore size between the nanofibers, and adding a second ceramic component to reduce the grain size. A ceramic nanofiber separation membrane according to an embodiment of the present invention includes the ceramic nanofiber structure and a photocatalytic inorganic coating layer. A separation membrane which has excellent optical resolution for organic matter and can retain decomposition efficiency for a long period of time can be obtained by including a highly flexible ceramic nanofiber structure and a photocatalytic inorganic coating layer formed on the surface of nanofibers.
