Abstract
The disclosure is directed at a large-area monolayer of solvent dispersed nanomaterials and method of producing same. The method of the disclosure includes dripping a nanomaterial solvent into a container filled with water whereby the nanomaterial being dripped collects at the air-water interface to produce the large-area monolayer. In one embodiment, different nanomaterial solvents can be dripped, at predetermined intervals such that the resulting large-area monolayer includes at least two different nanomaterials.
Claims8
A coated substrate comprising:
- A) a large-area monolayer film comprising a monolayer of nanomaterials comprising:
- a first nanomaterial generated via a dripping process onto an air-water interface in a water-filled container, the first nanomaterial comprising graphene oxide having a thickness in a range of approximately 0.5-1 nm as measured by atomic force microscopy;
- a second nanomaterial generated via a dripping process onto the air-water interface in the water-filled container, the second nanomaterial comprising MoS2;
- and,
- B) a solid substrate layer on which the monolayer film is deposited,
- wherein the first nanomaterial and the second nanomaterial abut each other edgewise to form an edge-to-edge interface between the first nanomaterial and the second nanomaterial, and
- wherein the substrate has an arbitrary length and the first nanomaterial and the second nanomaterial are successively arranged on the substrate along the length of the substrate with the edge-to-edge interface disposed width-wise on the substrate.
