Abstract

The main issues related with preparation of nanocomposites are dispersion, alignment and adhesion between carbon nanotubes and matrix. We are designing an approach where these issues are fully addressed. We combined a functionalization approach with in-situ technique of nanocomposites preparation. A good dispersion and intercalation of carbon nanotubes were observed in the prepared nanocomposites. A presence of strong interfacial region was also noted. It is also found that orientation of carbon nanotubes inside matrix can be done by mechanically stretching of nanocomposites. DSC analysis shows that inclusion of carbon nanotubes affects crystallization behavior of nylon 6 significantly and it is found that CNTs acts as nucleating agents.
