Abstract
Organized materials on a substrate. The organized materials are monolayer(s) of close-packed nanoparticles and/or microparticles. The organized materials can be formed by transfer of one or more monolayers to a substrate from a coating composition on which a monolayer of close-packed nanoparticles and/or microparticles is formed. Organized materials on a substrate can be used in devices such as, for example, batteries, capacitors, and wearable electronics.

A method of making an organized material on a substrate, wherein the organized material comprises one or more monolayers of nanoparticles disposed on at least a surface of a substrate and each monolayer of the layer is a close-packed arrangement of the nanoparticles, comprising:
- a) providing a coating composition in a container comprising:
- a monolayer of organized materials disposed on a liquid material comprising water and one or more additional liquid components that have lower surface tension than water, wherein the one or more additional liquid components is/are one or more alcohols;
- and
- b) transferring the monolayer of organized materials to the substrate, wherein the organized material on the substrate is formed.
A method of making an organized material on a substrate, wherein the organized material comprises one or more monolayers of organized materials disposed on at least a surface of a substrate and each monolayer is a close-packed arrangement of the organized materials, comprising:
- a) providing a coating composition in a container comprising:
- a monolayer of organized materials disposed on a liquid material comprising water and one or more additional liquid components that have lower surface tension than water, or
- a monolayer of organized materials disposed on a liquid material comprising water and a surfactant, wherein the surfactant does not function as a dispersant in the coating composition;
- and
- b) transferring the monolayer of organized materials to the substrate,
- wherein the organized material on the substrate is formed,
- wherein additional materials are added to the coating composition as the monolayer of organized materials is transferred to the substrate.
A method of making an organized material on a substrate, wherein the organized material comprises one or more monolayers of organized materials disposed on at least a surface of a substrate and each monolayer is a close-packed arrangement of the organized materials, comprising:
- a) providing a coating composition in a container comprising:
- a monolayer of organized materials disposed on a liquid material comprising water and one or more additional liquid components that have lower surface tension than water, or
- a monolayer of organized materials disposed on a liquid material comprising water and a surfactant, wherein the surfactant does not function as a dispersant in the coating composition;
- and
- b) transferring the monolayer of organized materials to the substrate,
- wherein the organized material on the substrate is formed,
- wherein the monolayer is transferred to a second substrate by physically contacting the organized material on the substrate with the second substrate and application of pressure.
A method of making an organized material on a substrate, wherein the organized material comprises one or more monolayers of nanoparticles disposed on at least a surface of a substrate and each monolayer of the layer is a close-packed arrangement of the nanoparticles, comprising:
- a) providing a coating composition in a container comprising:
- a monolayer of organized materials disposed on a liquid material comprising water and a surfactant, wherein a mixture of the materials and water is formed and, subsequently, the surfactant is added, and wherein the surfactant does not function as a dispersant in the coating composition;
- and
- b) transferring the monolayer of organized materials to the substrate,
- wherein the organized material on the substrate is formed, and
- wherein addition of the surfactant results in a surface tension gradient and formation of the organized monolayer of materials.
