  • Patent number: 9434620
    Abstract: The present invention relates to a foam-shaped graphene structure and, more particularly, to a method for producing a foam-shaped graphene structure by boiling, and to a foam-shaped graphene structure using same. Provided is a method for producing a foam-shaped graphene structure by boiling, which includes the steps of: preparing a base substrate (S1); placing the base substrate in a reduced graphene oxide (RGO) colloid solution (S2); applying a heat flux to the base substrate using an exothermic body so as to cause boiling (S3); and generating the foam-shaped graphene structure on the base substrate as bubbles generated by the boiling become overlapped (S4).
    Type: Grant

  • Publication number: 20110195107
    Abstract: The present invention provides a method for manufacturing a porous three-dimensional scaffold using animal tissue powder, comprising powdering an animal-derived tissue, decellularizing the animal-derived tissue before or after powdering it, or simultaneously with powdering it, and forming the decellularized animal-derived tissue powder into a porous three-dimensional scaffold by a particle leaching method.
