Influence of dispersion states of carbon nanotubes on mechanical and electrical properties of epoxy nanocomposites
752-756Multiwalled carbon nanotubes (MWCNTs)/ epoxy resin composites have been fabricated by dispersing very low
content (0.2%) of MWCNTs in the epoxy matrix using ethanol. To analyze dispersion of CNTs, optical microscope is used.
Further ductile nanocomposites (NCs) are prepared by setting samples at low temperature. With a little wt% of CNTs,
composite samples yield higher mechanical and electrical properties than pure resin samples. Improvement in flexural modulus
and electrical conductivity are observed in NCs containing well dispersed CNTs than the ones with poorly dispersed CNTs.
Lower values are due to inhomogeneous dispersion of nanotubes in polymer matrix. Moreover, ductile samples having better
dispersion state exhibit significant improvement in mechanical and electrical properties
