Abstract
High aspect-ratio metal members such as a nanopillar, a nanorod, and the like, and a method of producing the same. The present invention provides high aspect-ratio metal members such as a nanopillar or a nanorod, and a method of producing the same, such metal members being produced by filling the micropores of an anodized film having a degree of ordering of 70% or more with a metal having an aspect ratio of 5 or more, followed by baking in inert gas atmosphere or in a vacuum at 300° C. or more to 1000° C. or less to improve crystallinity.
Claims10
Metal members produced by filling a metal having an aspect ratio of 5 or more in micropores of an anodized film having a degree of ordering of 70% or more, followed thereafter by baking in inert gas atmosphere or in a vacuum at a temperature from 300° C. or more to 1000° C. or less to improve crystallinity.
Nanopillar metal members or nanorod metal members that are metal members having an aspect ratio of 5 or more produced by filling micropores of an anodized film having a degree of ordering of 70% or more with a metal having an aspect ratio of 5 or more, followed by baking in inert gas atmosphere or in a vacuum at a temperature from 300° C. or more to 1000° C. or less to improve crystallinity and removing the anodized film.
Metal members wherein a part or a whole of metal members are coated by at least one kind of noble metal, the metal members being nanopillar or nanorod metal members having a diameter of 0.02 μm to 0.4 μm, a length of 10 μm to 200 μm, and an aspect ratio of 5 or more.
A method of producing metal members having an aspect ratio of 5 or more, the method comprising filling a metal in the micropores of an anodized film to an aspect ratio of 5 or more, followed by baking in inert gas atmosphere or in a vacuum at a temperature from 300° C. or more to 1000° C. or less to improve crystallinity and removing the anodized film.
A method of producing nanopillar or nanorod metal members comprising filling a metal in the micropores of an anodized film to an aspect ratio of 5 or more, melting a part of the anodized film to expose the metal, coating an exposed region with a different kind of metal, and thereafter melting the anodized film.
