  • Patent number: 9181278
    Abstract: A method of preparing a carbon nanotube composite with metal particles on a surface thereof, including: introducing an acylhalide group to the surface, causing a reaction of the acylhalide group with an amine group of a polysiloxane to bond the polysiloxane to the surface by the amide groups, and introducing metal particles to other functional groups of the polysiloxane to bond the metal particles to the surface of the carbon nanotube composite.
    Type: Grant

  • Publication number: 20140316152
    Abstract: A carbon nanotube (CNT) composite of which one or more specific functional groups are bonded to surface of a CNT, and a method of preparing a CNT composite are provided. The method includes the steps of introducing an acylhalide group to surface of a CNT, and causing a reaction of the acylhalide group with a polysiloxane having amine groups so as to prepare a CNT composite of which the polysiloxane is bonded to the surface by the medium of an amide group. The CNT composite can fix metal particles uniformly and densely thereon, can have improved mechanical and electrical properties, and can be applied to various industrial fields.
