采用差示扫描量热法（DSC）研究了含有不同零维、一维和二维（0-D、1-D和2-D）纳米碳填料的高密度聚乙烯（HDPE）的等温和非等温结晶行为。在一定温度下，低维碳纳米填料的加入使HDPE的等温结晶孕育期延长，等温结晶速率减慢。Avrami指数和Tobin指数表明，在2-D和1-D碳纳米填料存在下，HDPE的等温结晶为二维晶体生长，而在0-D碳纳米填料存在下，HDPE的等温结晶为三维非均相晶体生长。与等温研究相反，低维纳米填料的存在加速了HDPE的非等温结晶。最后用Ozawa和Mo方法对非等温结晶数据进行了分析。结果表明，只有Mo模型能较好地描述HDPE和HDPE/碳纳米复合材料的非等温结晶过程。© 2012 Wiley Periodicals，Inc.

The isothermal and nonisothermal crystallization behavior of high density polyethylene (HDPE) containing various zero, one, and two dimensional (0-D, 1-D, and 2-D) carbon nanofillers were investigated by means of differential scanning calorimetry. For a given temperature, the isothermal crystallization incubation time of HDPE became longer with the addition of lower dimensional carbon nanofillers, and the isothermal crystallization rate got slower. The values of Avrami and Tobin exponents indicated that the isothermal crystallization of HDPE followed two-dimensional crystal growth in the presence of 2-D and 1-D carbon nanofillers, while exhibited three-dimensional heterogeneous crystal growth in the presence of 0-D carbon nanofillers. Contrary to the isothermal study, the nonisothermal crystallization of HDPE was accelerated in the presence of lower dimensional nanofillers. The nonisothermal crystallization data were finally analyzed using Ozawa and Mo methods. It was observed that only Mo approach could successfully describe the nonisothermal crystallization process of HDPE and HDPE/carbon nanocomposites. © 2012 Wiley Periodicals, Inc. J. Appl. Polym.
