Synthesis of carbon molecular sieve membrane from polymer precursor layers with zeolite nanosheet |
| 초록 |
Carbon membranes are usually prepared by pyrolysis of polymeric precursor membrane at high temperature under vacuum or inert atmosphere. Therefore, molecular sieving appears to be the main mechanism of carbon membrane. Supported membrane mainly uses alumina disk as a substrate. Because polymeric chains can penetrate relatively large pore-sized alumina disk, the supporting carbon membrane requires an additional process of intermediate layer coating. Without the intermediate layer, the manufacturing process of the carbon membrane can be reduced. An experiment was conducted to make a carbon membrane without intermediate layer with a solution. The solution made by mixing polymer and nanosheets with a wide surface area. The polymer solution mixed with nanosheets was coated on top of an alumina disk. We can make carbon membrane that is about 3μm thickness and has a gas separation performance. |
