New trend and joint ventures

Production of nanocomposite of Epoxy/Clay/CarbonNanotubes

CINVESTAV-Universidade do Estado de Santa Catarina (UDESC)-ITESM

Electrically conductive polymer composites made with

carbon nanotubes are of growing interest for a variety of

applications such as: electrostatic dissipation,

photovoltaic devices, and electromagnetic Interference

(EMI) shielding.


- Conductive polymer composites require a three

dimensional network to impart electrical

conductivity

  • Clay was introduced into single-walled carbon nanotube/epoxy

    composites to improve nanotube dispersion without harming

    electrical conductivity or mechanical performance

    - The montmorillonite clays, they have a layer based

    morphology,which spaces between such layers could be

    filled with material like water, gypsum, sand, other soil

    groups, lime, and organic additives or CARBON NANOTUBES to

    avoid the volumetric changes.
