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.

A method of producing a large-area monolayer of solvent dispersed nanomaterials comprising:
- dispersing nanomaterials in a water immiscible solvent to produce a nanomaterial solvent mixture;
- dripping, at predetermined time intervals, single drops of the nanomaterial solvent mixture into a water-filled container;
- and
- retrieving the large-area monolayer from the container.
Apparatus for producing a large-area monolayer of exfoliated nanomaterials comprising:
- a water-filled container;
- at least two different solvent dispersed nanomaterial solvent mixtures;
- and
- a dripping apparatus for dripping the at least two different solvent dispersed nanomaterial solvent mixtures, at predetermined time intervals, into the water-filled container.
A large area monolayer film comprising:
- a patterned first nanomaterial generated via a dripping process into a water-filled container;
- and
- a patterned second nanomaterial generated via a dripping process into a water-filled container;
- wherein the first and second nanomaterial abut each other.
