Abstract
A method of forming a transparent, electrically-conductive film and an associated film. The method can be a transfer method. A region of a substrate is provided with a binder that includes metal nanostructures suspended in a photosensitive polymeric material. A donor substrate can be used. Photolithography is used to pattern the binder. The patterned binder is developed using a developing fluid that: (i) removes a portion of the photosensitive polymeric material according to a pattern of the binder, and (ii) includes a nanostructure etchant that etches the metal nanostructures.
Claims19
A transfer method of forming a transparent, electrically-conductive film, the method comprising:
- providing a region of a donor substrate with a binder including metal nanostructures suspended in a photosensitive polymeric material;
- applying the donor substrate and the binder onto a receiver substrate;
- removing the donor substrate from the binder applied onto the receiver substrate;
- using photolithography to pattern the binder;
- and
- developing the patterned binder using a developing fluid that:
- (i) removes a portion of the photosensitive polymeric material according to a pattern of the binder, and (ii) includes a nanostructure etchant that provides for etching of the metal nanostructures.
