Title:
SEPARATION MEMBRANE COMPOSITE, SEPARATING DEVICE, SEPARATION METHOD, AND METHOD FOR PRODUCING SEPARATION MEMBRANE COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2022/130741
Kind Code:
A1
Abstract:
This separation membrane composite (1) comprises a support (11), a separation membrane (12), and a covering membrane (13). The support (11) has a porous section (41) and a compact section (42) that are disposed continuously. The separation membrane (12) is provided on the porous section (41) of the support (11). An end section of the separation membrane (12) is in contact with the compact section (42). The covering membrane (13) is formed from a layered inorganic compound. The covering membrane (13) covers a boundary section (45) between the compact section (42) and the separation membrane (12). This makes it possible to improve the separation performance of the separation membrane composite (1). Additionally, the covering membrane (13) can easily be formed.
