采用旋转啮合双螺杆挤出机制备了多壁碳纳米管填充聚丙烯复合材料。为了提高MWCNT的分散性，采用1,10-二氨基癸烷对MWCNT表面进行改性，并以马来酸酐接枝聚丙烯（MA-g-PP）作为相容剂。由于MA-g-PP和二胺- mwcnt在PP/MA-g-PP/二胺- mwcnt复合材料中发生反应，观察到分散良好的功能化MWCNTs（二胺- mwcnt）的显微照片。与PP和PP/ neet - mwcnt相比，观察了PP/MA-g-PP/二胺- mwcnt复合材料在结晶和熔融温度方面的不同行为。与PP相比，复合材料的分解温度提高了50℃，其中PP/MA-g-PP/二胺- mwcnts复合材料的复合粘度最高。©2008 Wiley期刊公司高分子学报，2009
Multi-walled carbon nanotubes (MWCNTs) filled polypropylene (PP) composites were prepared by a corotating intermeshing twin screw extruder. To improve the dispersion of MWCNTs, the surface of MWCNT was modified with 1,10-diaminodecane, and maleic anhydride grafted polypropylene (MA-g-PP) was used as a compatibilizer. Micrographs of well dispersed functionalized MWCNTs (diamine-MWCNT) were observed due to the reaction between MA-g-PP and diamine-MWCNT in PP/MA-g-PP/diamine-MWCNTs composites. The different behaviors in crystallization and melting temperatures of PP/MA-g-PP/diamine-MWCNTs composite were observed compared to PP and PP/neat-MWCNT. Especially, the decomposition temperature of the composite was increased by 50°C compared to PP. PP/MA-g-PP/diamine-MWCNTs composite showed the highest complex viscosity. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
