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. La présente invention concerne une monocouche à grande surface de nanomatériaux dispersés dans un solvant et son procédé de production. Le procédé selon l'invention consiste à faire couler goutte-à-goutte un solvant de nanomatériau dans un contenant rempli d'eau de sorte que le nanomatériau qui s'écoule goutte-à-goutte se rassemble au niveau de l'interface air-eau pour produire une monocouche à grande surface. Dans une forme de réalisation, différents solvants de nanomatériau peuvent être versés en mode goutte-à-goutte, à des intervalles prédéterminés de sorte que la monocouche à grande surface résultante inclue au moins deux nanomatériaux différents.
