This invention generally relates to a device for preparing and transferring a monolayer or thin film. In particular this present invention is a device for preparing and transferring a monolayer or thin film to a substrate using an improved version of the Langmuir-Schaefer technique, which incorporates in situ thermal control, for instance to heat the supporting substrate before and/or during the transfer process.

A large-area monolayer of solvent dispersed nanomaterials and method of producing same is provided. The method 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 for producing an anode for a lithium metal secondary battery includes coating a thin film comprised of Nb.sub.2C, Ti.sub.2C or Ti.sub.3C.sub.2 on a substrate; providing a lithium metal electrode; and laminating the thin film to a surface of the lithium metal electrode. Coating is accomplished by providing a dispersion of a powder comprising Nb.sub.2C, Ti.sub.2C or Ti.sub.3C.sub.2; and coating the dispersion on the substrate by Langmuir-Blodgett scooping (LBS). The method may further include, prior to providing the dispersion, obtaining the powder by etching a MAX phase structure represented by Formula 1, Formula 2 or Formula 3 below:
Nb.sub.2AC(1);
Ti.sub.2AC(2); and
Ti.sub.3AC.sub.2(3), where A is a metal selected from among Group IIIA elements, Group IVA elements, Cd, and combinations thereof. The method may further include, after laminating the thin film, removing the substrate from the thin film.

The present invention generally relates to a method for creating a chemically structured surface with structural elements as small as 1 nm, on a material that does not itself display a high degree of ordering, using thin molecular layers that minimize the material added through the coating. In particular, the present invention discloses a method for assembling a chemical pattern on a surface, comprising pattern elements with scales that can be as small as 1 nm, and then transferring that pattern to another substrate, on which the pattern would not form natively. In the described method, the patterned monolayer is comprised of polymerizable amphiphiles such as diyne phospholipids or diynoic acids, which are transferred from the ordering substrate using a transferring material such as poly(dimethylsiloxane).

According to the present invention, an ultra-fast method for preparing an organic/inorganic thin film by using self-diffusion effects comprises the steps of: forming a solution by dissolving one or more organic/inorganic materials in a solvent; forming an organic/inorganic thin film by supplying the formed solution onto a liquid substrate; and transferring the formed thin film to a substrate, wherein the step of forming an organic/inorganic thin film forms a thin film on the liquid substrate from the organic/inorganic materials through the occurrence of a self-diffusion phenomenon caused by a difference in surface tension between the liquid substrate and the solution, and through the occurrence of the evaporation of the solvent and the dissolution process of the solvent to the liquid substrate.

This invention discloses a method for controlling nanoscopic wetting near or at a molecular scale for synthetic material applications. In particular this invention relates to a method for preparing a monolayer or thin film with a patterned nanoscopic wetting surface using a sitting phase of polymerizable amphiphile, wherein hydrophobic alkyl chains of the amphiphile extend along the supporting surface and the amphiphile molecules align side-to-side, effectively forming a repeating cross-section of bilayer with alternating hydrophilic and hydrophobic stripes of a 6 nm pitch tunable based on the chain length of the amphiphile. Products prepared according to the methods disclosed herein are within the scope of this invention. In some embodiments, monolayers or thin films so prepared are transferable.
