  • Patent number: 9802819
    Abstract: Disclosed herein are a conducting network for storing gas such as hydrogen, carbon dioxide, or the like, and a method for preparing the same, and particularly, a conducting network composite including: dopant-doped polyaniline nanofiber supporter; and a polypyrrole layer laminated on the supporter, and a method for preparing the same. According to the present invention, a novel conducting network composite suitable for being used as an energy storage material for various purposes may be provided by a simple and economical method, and since a polyaniline nanofiber having the entangled structure may function as an excellent supporter for forming a network composite material and a thickness of the polypyrrole layer may be easily adjusted, the nanocomposite for being used in various fields may be simply and economically prepared.

  • Publication number: 20140378563
    Abstract: Disclosed herein is a method for preparing a nanoporous polypyrrole for storing gas such as hydrogen, carbon dioxide, or the like, and a nanoporous polypyrrole prepared therefrom. More particularly, disclosed herein are a solid state vapor phase polymerization method for nanoporous polypyrrole, the method comprising dispersing a solid state oxidant on a substrate; exposing the substrate and the oxidant to vapor phase pyrrole monomers to perform a polymerization reaction of the pyrrole monomers to thereby prepare a solid state polypyrrole; and cleaning and drying the solid state polypyrrole; and a nanoporous polypyrrole prepared therefrom.

  • Publication number: 20120225126
    Abstract: Disclosed are a solid state synthesis method of silver nanoparticles, and silver nanoparticles synthesized thereby. The method includes mixing a silver salt and a water soluble polymer acting as both a reducing agent and a protecting agent to produce a solid mixture, and milling the solid mixture by a high-speed vibration milling process to form silver nanoparticles within the water soluble polymer. According to the present invention, silver nanoparticles can be easily and simply produced in a solid state through high speed vibration milling, thereby reducing costs for industrial production and transportation of silver nanoparticles. In addition, the synthesized silver nanoparticles can be used for a long time since the silver nanoparticles are stable in a solid state for 1 year or more.

  • Publication number: 20090092836
    Abstract: A gold nanoparticle-halloysite nanotube, on a surface of which a gold nanoparticle is formed, and a method for forming the same are disclosed. In order to form the gold nanoparticle on a surface of the halloysite nanotube, a gold salt is added to an agitated suspension solution. By the gold salt, a gold ion is formed on the surface of the halloysite nanotube. If the reducing agent is added to the halloysite nanotube on which the gold ion is formed, the gold ion is reduced into the gold nanoparticles. The formed gold nanoparticle has the very small size, and distributed on the surface of the halloysite nanotube. Accordingly, without the separate protective agent or the surface reformation, the gold nanoparticle may be easily formed.
