Abstract
An apparatus and method for transferring nanofiber structures (e.g., nanofiber films, nanofiber sheets, stacks of nanofiber grids, nanofiber films, nanofiber sheets, and combinations thereof) between various substrates are described. The techniques described use a soluble layer on a substrate that is subsequently dissolved, thus freeing the nanofiber structure from the substrate. This liquid phase techniques preserves the mechanical integrity and the purity of the nanofiber structures.
Claims20
A method comprising:
- preparing a nanofiber structure on a substrate assembly, the substrate assembly including a substrate layer and a soluble layer;
- dissolving the soluble layer with a solvent;
- in response to the dissolving, floating the nanofiber structure on a surface of the solvent;
- and
- causing detachment of the nanofiber structure from the substrate layer as the nanofiber structure is submerged into the solvent.
2 more elements
An apparatus, comprising:
- a transparent conductive film comprising:
- a nanofiber structure on a substrate assembly, the substrate assembly including a substrate layer and a soluble layer;
- wherein the nanofiber structure is configured to float on a surface of a solvent and wherein the soluble layer is configured to be dissolved from the substrate layer by floating the nanofiber structure on the surface of the solvent.
