Abstract
The present disclosure relates to methods for producing large scale nanostructured material comprising carbon nanotubes. Therefore, there is disclosed a method for making nanostructured materials comprising depositing carbon nanotubes onto at least one substrate via a deposition station, wherein depositing comprises transporting molecules to the substrate from a deposition fluid, such as liquid or gas. By using a substrate that is permeable to the carrier fluid, and allowing the carrier fluid to flow through the substrate by differential pressure filtration, a nanostructured material can be formed on the substrate, which may be removed, or may act as a part of the final component.
Claims47
A method of making a nanostructured material comprising carbon nanotubes, said method comprising:
- suspending carbon nanotubes in a carrier fluid to form a mixture,
- inducing said mixture to flow through a substrate that is permeable to the carrier fluid by differential pressure filtration,
- depositing said carbon nanotubes from said mixture onto said substrate to form a nanostructured material.
A continuous or semi-continuous method of making a nanostructured material comprising carbon nanotubes, said method comprising:
- suspending carbon nanotubes in a carrier fluid to form a mixture,
- inducing said mixture to flow through a moving substrate that is permeable to the carrier fluid by differential pressure filtration,
- depositing said carbon nanotubes from said mixture onto said moving substrate to form a nanostructured material having a length greater than 1 meter.
A method of making a nanostructured material for filtering at least one contaminated fluid, said method comprising:
- suspending carbon nanotubes and glass fibers in a carrier fluid to form a mixture,
- inducing said mixture to flow through a substrate that is permeable to said carrier fluid and said contaminated fluid by differential pressure filtration, and
- depositing said carbon nanotubes from said mixture onto said substrate to form a nanostructured material.
