Molecular filtration by ultrathin nanofilm composite membrane of organic molecular nets |
| 초록 |
A new nanofilm composite (NFC) membrane is demonstrated. A solution-based molecular layer deposition (MLD) is conducted on a nanoporous alumina support to fabricate molecular nets as an ultrathin skin layer. Alternating deposition of multi-functional, tetrahedral molecules gives nanometer thick films of three-dimensionally cross-linked organic molecular networks. Varying the number of deposition cycles enables to control the pore size of the NFC membrane precisely on the molecular level. The morphology of the membrane is studied using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The flux and rejection of the NFC membrane is investigated by filtration of the solutions containing organic solutes. This work is supported by a Korea Science and Engineering Foundation (KOSEF) grant [2010-0026421] funded by the Korean government (MEST). |
