Multi-walled carbon nanotubes (MWNTs) were functionalized with a silane coupling agent. The MWNTs were first coated with inorganic silica by a sol-gel process and then grafted with 3-methacryloxypropyltrimethoxysilane (3-MPTS).通过偏光光学显微镜、差示扫描量热法和广角 X 射线衍射研究了原始 MWNT 和硅烷官能化 MWNT 对聚丙烯 (PP) 结晶行为的影响。等温结晶实验结果表明，3-MPTS功能化显着影响PP/MWNTs复合材料的结晶和熔融行为，这可能是由于MWNTs的3-MPTS功能化导致MWNTs在PP基体中均匀分散，从而使MWNTs具有良好的成核效果。 © 2007 Wiley Periodicals, Inc.

Multi-walled carbon nanotubes (MWNTs) were functionalized with a silane coupling agent. The MWNTs were first coated with inorganic silica by a sol-gel process and then grafted with 3-methacryloxypropyltrimethoxysilane (3-MPTS). The effect of raw MWNTs and silane-functionalized MWNTs on the crystallization behavior of poly(propylene) (PP) was investigated by means of polarized optical microscopy, differential scanning calorimetry, and wide-angle X-ray diffraction. Results obtained from isothermal crystallization experiments indicate that 3-MPTS functionalization affects the crystallization and melting behavior of PP/MWNTs composites remarkably, which can be attributed to the fact that 3-MPTS functionalization of MWNTs leads to a uniform dispersion of MWNTs in PP matrix resulting in the good nucleating effect of MWNTs. © 2007 Wiley Periodicals, Inc.
