摘要： The present invention relates to a method for preparing a nanosheet including the steps of: depositing a solution onto a substrate to form a first layer, wherein the substrate is rotatable relative to the depositing solution; depositing and condensing target material onto the first layer to form a second layer; and separating the second layer from the first layer and the substrate to form a nanosheet. Also disclosed a multilayer structure including: a substrate; a first layer arranged to deposit onto the substrate, wherein the substrate is rotatable relative to the depositing of the first layer; and a second layer arranged to deposit onto the first layer and separable from the first layer to form a nanosheet.

摘要： The present invention provides a metal-carbon composite of a core-shell structure and a method of synthesizing the same. The method includes preparing a first polymer-covered glass substrate with a nano-thickness metal film deposited thereon; immersing the first polymer-covered glass substrate with the metal film to delaminate one or more 2D freestanding organic-metal nanosheets from the first polymer-covered glass substrate; transferring the one or more 2D freestanding organic-metal nanosheets onto a second target substrate; and annealing the one or more 2D freestanding organic-metal nanosheets to decompose an organic portion of the organic-metal nanosheet into an amorphous carbon-containing shell forming a metal-carbon nanocomposite of a core-shell structure.
