Abstract: The present invention relates to a method for manufacturing graphene, comprising: (i) an electron beam irradiation process for primarily exfoliating graphite by irradiating the graphite with an electron beam; (ii) a sulfuric acid soaking process for manufacturing graphene by secondarily exfoliating the graphite in the process of secondarily soaking the graphite, which has been primarily exfoliated in the electron beam irradiation process, in sulfuric acid; (iii) a washing and filtering process for filtering the graphene after washing the graphene manufactured in the sulfuric acid soaking process; and (iv) a dispersion process for treating the graphene with supersonic waves after soaking the graphene, which has passed through the washing and filtering process, in a surface active agent. The present invention can manufacture highly exfoliated graphene effectively because the present invention manufactures graphene by primarily exfoliating graphite in the process of irradiating the graphite with an electron beam and secondarily exfoliating the graphite in the process of soaking the primarily exfoliated graphite in sulfuric acid. In addition, the present invention is eco-friendly by minimizing the use of chemicals and can minimize damage to graphene that is generated in a graphene-manufacturing process.

Abstract: A nano fiber filament with a thin membrane of polymer and a manufacturing method thereof are provided to stack a multi-layer electrolyte polymer thin film with a nano scale on a nano fiber filament, thereby increasing largely the mechanical property. In a pre-treatment process, a base member(1) of a nano fiber filament consisting of the nano fiber of the average diameter of below 1,000mm is immersed into the polar polymer electrolytic solution including ions of identical charges and thereafter washed. In the first thin film forming process, the pre-treated base member is immersed into the polar polymer electrolytic solution including ions of opposite charges and thereafter washed. In the second thin film forming process, the base member after the first thin film forming process is immersed into the polar polymer electrolytic solution including ions of opposite charges and thereafter washed. The first and second thin film form processes are repeated alternately 1 to 10 times.

Abstract: The present invention relates to a method for preparing a hydrogel having excellent biocompatibility by using a keratin derivative extracted from hairs of animals. The method of the present invention comprises: (i) a process of dissolving a keratin derivative, which is extracted from hairs of animals including a human being, in water to prepare an aqueous keratin derivative solution; (ii) a process of adding and dissolving polyvinyl alcohol and polyethylene imine into the aqueous keratin solution to prepare an aqueous mixture solution; and (iii) a process of performing a radiation treatment on the aqueous mixture solution. According to the present invention, a hydrogel useful for wound healing and skin regeneration because of eco-friendly and biocompatible characteristics thereof can be prepared by using only a low dose of radiation and at least chemicals, and thus can minimize environmental pollution and energy consumption. Further, according to the present invention, the radiation treatment leads to sterilization in addition to the preparation of the hydrogel, thereby skipping a post process for treating toxic materials.
