Abstract
A collecting filter has a filter membrane with a porous structure to filter a nanocarbon material from a dispersion medium containing the nanocarbon material, and a dense film having an opening through which the dispersion medium passes. The opening has a reverse tapered shape in which a first width at an inlet of the dispersion medium opposite to the filter membrane is smaller than a second width at a bottom side adjacent to the filter membrane.
Claims6
A collecting filter comprising:
- a filter membrane having a porous structure to filter a nanocarbon material from a dispersion medium containing the nanocarbon material, the filter membrane having one surface;
- and
- a dense film formed on the one surface and having an opening through which the dispersion medium passes, the dense film having a denseness to block passage of the dispersion medium in a portion different from the opening, wherein
- the opening has a first width at an inlet of the dispersion medium opposite to the filter membrane and a second width at a bottom side adjacent to the filter membrane, and
- the first width is smaller than the second width.
