Crystallization Behavior of SWNTs-PP Nanocomposites Prepared by Latex Technology

摘要：

The conductive single wall carbon nanotubes- polypropylene (SWNTs-PP) nanocomposites were prepared based on latex technology. An extreme low conduction threshold of 0.075wt％ with saturation conductivity of 0.5S/m was achieved. The nonisothermal crystallization of SWNTs-PP nanocomposites was investigated by means of differential scanning calorimetry, X-ray diffraction and optical electron microscopy. The results showed that the SWNTs acted as nucleating agent in PP. Accordingly, the crystallization and melting temperature increased with increasing of the SWNTs content, and the spherulite size decreased. The crystallinity and crystallite size both increased with the addition of SWNTs and then decreased after the SWNTs content was beyond 0.1wt％ and 0.01wt％, respectively.
