This invention generally relates to a method for preparing and transferring a monolayer or thin film. In particular this present invention is an improved version of the Langmuir-Schaefer technique for preparing and transferring a monolayer or thin film, incorporating in situ thermal control of the substrate during the transfer process.

In an example, a method including dispensing a liquid onto a first portion of a surface of a substrate and dispensing a solution comprising colloidal spheres onto a second portion of the surface of the substrate. The method additionally includes agitating the colloidal spheres to disperse the colloidal spheres along the first portion and the second portion of the surface of the substrate and directing air flow above the colloidal spheres inducing rotation of the colloidal spheres. In another example, a method includes positioning a retaining ring on a surface of a liquid above a substrate below the surface of the liquid and dispensing a solution comprising colloidal spheres onto the surface of the liquid within a surface area of the retaining ring. The method further includes agitating the surface of the liquid and the colloidal spheres to disperse the colloidal spheres along the surface area of the retaining ring.

A composition includes a polymer and a solvent. The polymer includes: a structural unit including a ring structure; and a functional group capable of bonding to a metal atom. An atom chain constituting the ring structure constitutes a part of a main chain of the polymer. The polymer preferably includes at an end of the main chain or at an end of a side chain, a group including the functional group. The functional group is preferably a cyano group, a phosphono group, or a dihydroxyboryl group. The ring structure preferably includes an alicyclic structure.

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 method for preparing a nanowire or nanorod on a patterned monolayer or thin film supported by a 2D material substrate in a nonpolar environment comprises the steps of: functionalizing a supporting 2D material substrate using a patterned monolayer or thin film of a polymerized amphiphiles comprising both hydrophobic and hydrophilic constituents; and then growing a nanowire or nanorod on the functionalized supporting 2D material substrate in a salt solution or suspension, wherein the patterned monolayer or thin film comprises a polymerizable phospholipid with a terminal amine. A gold nanowire or nanorod so prepared has a highly controlled diameter of about 2 nm, and a length of about 100 nm, dependent in part on molecular domain sizes in the monolayer.
