New trend and joint ventures
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.
