Patterning a nanofiber forest
Abstract:
A nanofiber forest that includes a pattern or shape can be transferred to a substrate. The nanofiber forest can be configured to have any perimeter and/or internal shape or pattern using a stencil technique and/or using an engraving technique. This pattern can be transferred as a “negative image” of a corresponding pattern in a stencil or as a “positive image” by engraving the pattern directly into the nanofiber forest. For either type of pattern formation, the patterned nanofiber forest is transferred by applying a substrate to the pattern or to a nanofiber forest covered by a patterned stencil. Pressure is then applied causing the exposed surface of the nanofiber forest or pattern of nanofiber forest to adhere to the substrate.
