Abstract
Provided herein is a device for forming a conductive film. The device includes a deposition device and an air supply. The deposition device is configured to form a wet film having conductive nanostructures and a fluid carrier on a web. The web is moved in a first direction while forming the wet film. The air supply is disposed at a side of the web and configured to apply an air flow onto the wet film. The air flow is directed onto the wet film in a second direction perpendicular to the first direction to reorient a direction of some conductive nanostructures in the wet film to define reoriented conductive nanostructures.
Claims9
A conductive film, comprising:
- a plurality of conductive nanostructures, wherein:
- at least some of the plurality of conductive nanostructures are reoriented,
- the conductive film has a first dimension and a second dimension perpendicular to the first dimension,
- both the first dimension and the second dimension are perpendicular to a normal of the conductive film,
- the conductive film has an anisotropy, which is defined as a ratio (RTD/RMD) of a first sheet resistance (RMD) and a second sheet resistance (RTD),
- the first sheet resistance (RMD) is measured at a given location along the first dimension and the second sheet resistance (RTD) is measured at the given location along the second dimension, and
- the anisotropy is greater than 1 and less than 2 according to a reorientation of the at least some of the plurality of conductive nanostructures.
