  • MAGNETIC NANOPARTICLES DECORATED ACTIVATED CARBON NANOCOMPOSITES FOR PURIFICATION OF WATER
    Publication number: 20160243523
    Abstract: The present invention relates to the development of water purifying compositions based on magnetic nanoparticles decorated activated carbon nanocomposites which display both magnetic character as well as adsorbent characteristics. The addition of adsorbent to impure water containing dye as pollutant enables the fast adsorption of dye leading to discoloration of water whereas magnetic properties facilitates the rapid isolation of pollutant adsorbed nanocomposites powder from the purified water with the aid of a magnet. The present invention also provides a process for the development of such multifunctional adsorbent using a process which enables decoration of adsorbent with 5-50 weight % of magnetic nanoparticles, the enables the realization of magnetic adsorbent having saturation magnetization in the range 0.09 to 28.3 emu/g, dye removal efficiency of >99%, rapid decolourization of methylene blue (MB)/methyl orange (MO) dye polluted water in less than 1 min, magnetic separation time in the range <0.

  • LIGHT WEIGHT CARBON FOAM AS ELECTROMAGNETIC INTERFERENCE (EMI) SHIELDING AND THERMAL INTERFACE MATERIAL
    Publication number: 20150305211
    Abstract: The present invention deals with the development of light weight carbon foam from coal tar pitch as electromagnetic interference (EMI) shielding and thermal interface material for aerospace and aircraft systems protection. The carbon foam developed from mixing the MWCNTs in starting material in different weight fraction and also MWCNTs decorated on the carbon foam by chemical vapor deposition technique gives improved electromagnetic interference (EMI) shielding.

  • Conducting copolymer ferromagnetic composite and a process for the preparation thereof
    Patent number: 8277690
    Abstract: The present invention provides a conducting copolymer ferromagnetic composite. Particularly, the present invention relates to a conducting copolymer of aniline and ethylene-dioxy thiophene containing ferrite particles. The present invention also provides insitu polymerization of aniline and ethylene-dioxy thiophene in the presence of ferrite particles and suitable surfactant medium. This conducting copolymer ferromagnetic composite can be used for the dissipation of electrostatic charge, for the shielding of electromagnetic interference and as absorbing of electromagnetic waves in the microwave region.
