  • Polyaniline/carbon black composite and preparation method thereof
    Patent number: 7795331
    Abstract: A polyaniline/carbon black composite and a preparation method thereof are disclosed The polyaniline/carbon black composite is formed by polyaniline covering carbon black and is with core-shell structure while the polyaniline/carbon black composite contains 10˜30 wt. % of carbon black. The preparation method of polyaniline/carbon black composite includes the steps of: disperse carbon black into solution to form carbon black solution, add aniline into the carbon black solution to form a first solution; dissolve ammonium persulfate into acid aqueous solution to form a second solution; add the second solution to the first solution, after reaction, through filtering and grinding to produce polyaniline/carbon black composite.
    Type: Grant
    Filed: July 7, 2009
    Date of Patent: September 14, 2010
    Assignee: Chung Shan Institute of Science and Technology, Armaments Bureau, M.N.D.
    Inventors: Cheng-Chien Yang, Kuo-Hui Wu, Wang Tsae Gu, Yuen-Hsin Peng, Zhi-Han Liu
