    摘要： Provided are a method of preparing a graphene shell and a graphene shell prepared using the method. A first heat treatment is performed on a mixture of an organic solvent and a graphitization catalyst so as to carburize the graphitization catalyst with carbon decomposed from the organic solvent. The graphitization catalyst is in the form of particles. A second heat treatment process is performed on the carburized graphitization catalyst in an inert or reductive gas atmosphere to thereby form graphene shells on surfaces of the carburized graphitization catalyst.

    摘要： Disclosed are a carbon nano-tube (CNT) light emitting device and a method of manufacturing the same. Specifically, the CNT light emitting device comprises: a CNT thin film formed using a CNT dispersed solution; a n-doping polymer formed on one end of the CNT thin film; a p-doping polymer formed on the other end of the CNT thin film; and a light emitting part between the n-doping polymer and the p-doping polymer. In addition, the method of manufacturing a CNT light emitting device comprises steps of: mixing CNTs with a dispersing agent or dispersing solvent to prepare a CNT dispersed solution; forming a CNT thin film using the CNT dispersed solution; coating a n-doping polymer on one end of the CNT thin film; and coating a p-doping polymer on the other end of the CNT thin film. According to the invention, the n-doping polymer and the p-doping polymer are respectively coated on the CNT having a CNT random network structure to implement a p-n junction, thereby implementing a light emitting device in a simple and low-priced process.

    摘要： A method of fabricating a liquid film is provided. The method comprises the steps of applying hydrophilic liquid onto a substrate with an electrode formed thereunder, covering the hydrophilic liquid with a protection film comprising hydrophobic liquid, dispersing surfactant for reducing the surface tension between the hydrophilic liquid and the protection film, and applying voltage to the hydrophilic liquid and the electrode to wet the substrate with the hydrophilic liquid. With the surfactant and the electro-wetting principle, a contact angle between the hydrophilic liquid and the substrate is controlled. The liquid film having a uniform thickness in nano size is thus formed on the substrate. The protection film prevents the evaporation of the liquid film in the air to thereby secure the stability of the liquid film.
