Production of nanocomposite of Epoxy/Clay/Carbon Nanotubes

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

Electrically conductive polymer composites made withcarbon nanotubes are of growing interest for a variety

ofapplications such as: electrostatic dissipation,photovoltaic devices, and electromagnetic

Interference(EMI) shielding.

- Conductive polymer composites require a threedimensional network to impart electricalconductivity

- Clay was introduced into single-walled carbon nanotube/epoxycomposites to improve nanotube dispersion without harmingelectrical conductivity or mechanical performance

- The montmorillonite clays, they have a layer basedmorphology,which spaces between such layers could befilled with material like water, gypsum, sand, other soilgroups, lime, and organic additives or CARBON NANOTUBES toavoid the volumetric changes.
