AI Technical Summary
Technical Problem
Existing zeolite membrane composites are prone to defects such as cracks during manufacturing, which leads to a decline in separation performance. Furthermore, the repair methods are complex, costly, and slow down the separation speed.
Method used
Layered inorganic compounds, such as clay minerals or layered metal oxides, are used to form a coating membrane that covers the dense portion and the boundary portion of the separation membrane, thereby improving separation performance and simplifying the manufacturing process.
Benefits of technology
It enhances the separation performance of the separation membrane composite, simplifies the manufacturing process, reduces costs, and increases separation speed.

Abstract
分离膜复合体(1)具备：支撑体(11)、分离膜(12)、以及被覆膜(13)。支撑体(11)具有连续配置的多孔质部(41)及致密部(42)。分离膜(12)设置于支撑体(11)的多孔质部(41)上。分离膜(12)的端部与致密部(42)接触。被覆膜(13)由层状无机化合物形成。被覆膜(13)将致密部(42)和分离膜(12)的边界部(45)被覆。据此，能够提高分离膜复合体(1)的分离性能。另外，能够容易地形成被覆膜(13)。
