Abstract: The present disclosure relates to a polymer-based large-area carbon nanomesh and a method for preparing same. More particularly, the present disclosure provides a method for preparing a carbon nanomesh, including: preparing a polymer nanofilm by coating a solution of a block copolymer or a polymer mixture thereof on a substrate; stabilizing the polymer nanofilm by annealing such that the polymer nanofilm is phase-separated, a pore-forming polymer is removed and, at the same time, a nanomesh-forming polymer forms a stabilized porous polymer nanomesh; and carbonizing the stabilized porous polymer nanomesh by annealing at high temperature to prepare a carbon nanomesh. Using phase separation and cyclization of a polymer, a large-area carbon nanomesh with superior activity can be prepared simply with high reproducibility in large scale.

Abstract: A fiber-type electronic device comprising a pattern for electronic devices stacked on a fiber filament substrate is provided. It is possible to manufacture an electronic device directly on a fiber filament substrate by applying the pattern for electronic devices. Thus, it can be widely used for wearable devices and the like. The pattern for electronic devices is manufactured by a method for forming a pattern for electronic devices comprising an exposure process using a maskless exposure apparatus. Thus, it is possible to manufacture a pattern for electronic devices on a fiber filament substrate through a continuous process and thus to increase the process efficiency.

Abstract: Provided are nitrogen-doped carbon quantum dots as pyrolysis product of fumaronitrile. The carbon quantum dots may be formed in such a manner that nitrogen may be doped in an amount of 3-10 wt % based on the total weight of the carbon quantum dots with no need for a separate doping process. As a result, the carbon quantum dots have excellent properties, such as optical property, electroconductivity and thermal safety, and thus may be useful for photocatalysts or organic solar cells, or the like.

Abstract: Provided is a method for preparing a carbon material based on an organic nanofilm using thermal evaporation, including: depositing a liquid polymer or polymer solution containing a polymer and a solvent onto a substrate, thereby forming an organic nanofilm; stabilizing the organic nanofilm so that the carbon atoms in the organic nanofilm have a cyclic arrangement; and carbonizing the stabilized organic nanofilm, thereby forming a carbon material, wherein the organic nanofilm is formed from the liquid polymer or polymer solution through a thermal evaporation process. The method provides a carbon material with a thickness, sheet resistance and surface roughness suitable for various applications and allows control thereof. In addition, the method uses a relatively inexpensive starting material, pitch, thereby reducing the overall production cost, and avoids a need for a complicated additional patterning operation, so that the carbon material is applied directly to electronic devices.
