摘要

This study reports an investigation on the effect of non-ionic surfactant (Triton X-100) on the dispersion of multiwalled carbon nanotubes (MWNTs) inside the polymer matrix. Adsorption of triton X-100 to the MWNTs was confirmed through FTIR. A reduced bundling of MWNT fibrils were noticed in Triton X-100 modified MWNTs (Tr-MWNTs). The polymer nanocomposites were prepared via melt blending technique. The optimization of loading ratio of the MWNTs and Tr-MWNTs was carried out on the basis of mechanical properties. Dynamic mechanical analysis exhibited the much uniform dispersion of the Tr-MWNT inside polymer matrix as compared to that of MWNTs. A faster rate of crystallization was noticed in case of MWNT reinforced nanocomposites, however, a strong filler-polymer interaction could be seen in case of Tr-MWNT filled nanocomposites. Optical microscopic analysis exhibited similar effect of MWNT and Tr-MWNT on the spherulite size of the polymer.
