| Outline of Final Research Achievements |
Nanoporous carbon membranes were successfully obtained from graphite targets by using the magnetron sputtering method at room temperature. The characteristics of the newly prepared nanoporous carbon membranes were investigated using X-ray reflectivity (XR), ellipsometry, and X-ray photoelectron spectroscopy (XPS) methods. The results indicated that the nanoporous carbon membranes possess relatively low density and refractive index, nevertheless they consist of sp3 and sp2 bonds as same as diamond-like carbon. Interestingly, our carbon membrane showed outstanding filtration properties. These filtration properties and porous structure may relate to its low density and refractive index. A more conclusive study including these effects will be reported in the near future.
