| Abstract: | Carbon nanotube based epoxy composites have been fabricated at room temperature and refrigeration process using sonication
principle. Flexural moduli, electrical conductivity, glass transition temperature of epoxy resin as well as nanocomposite
samples have been determined. Distribution behaviour of carbon nanotubes in the epoxy matrix was examined through scanning
electron microscopy. Composite samples showed better properties than resin samples due to strengthening effect of the filled
nanotubes. Refrigerated nanocomposites obtained increasing mechanical property because of better dispersion due to low temperature
settlement of polymers. Improvement of electrical conductivity was due to the fact that aggregated phases form a conductive
three-dimensional network throughout the whole sample. The increasing glass transition temperature was indicative of restricting
movement of polymer chains that ascribe strong interaction presented between carbon nanotubes and epoxy chains that was again
supplemented by Raman study and SEM. |
