  • Publication number: 20180054926
    Abstract: An electromagnetic wave shielding sheet including a carbon composite fiber and manufactured by electrospinning, and a method of manufacturing the same are disclosed. More particularly, an electromagnetic wave shielding sheet includes a carbon composite fiber having a core-shell structure and a resin, and the core-shell structure includes an outer shell including a carbon fiber, and a core including metal nano particles arranged in a length direction of the carbon fiber in the outer shell. The electromagnetic wave shielding sheet includes metal nano particles as electromagnetic wave shielding materials in a carbon fiber, and the oxidation of a metal may be prevented, conductivity in a length direction of the carbon fiber may be secured, and the sheet may be applied to various industrial fields as an electromagnetic shielding material.

  • Patent number: 9697931
    Abstract: Provided are a method of preparing a large-area, three-dimensional graphene transparent electrode using an electrospray deposition method and a large-area, three-dimensional graphene transparent electrode prepared therefrom. More particularly, the present invention is related to a method of preparing a large-area, three-dimensional graphene transparent electrode using an electrospray deposition method, which may easily prepare a large-area graphene transparent electrode having high transparency and conductivity through an electrospray process and may obtain effects, which may not be realized in a two-dimensional transparent electrode prepared by a typical method such as CVD, due to a three-dimensional stack structure in which graphene is arranged perpendicular to a substrate, and a large-area, three-dimensional graphene transparent electrode prepared therefrom.
