Abstract

It is shown that theoretical models elaborated for polymer microcomposites are not capable to describe variation of the melt viscosity of polypropylene/globular carbon nanocomposites at change in the nanofiller contents. Then a fractal model of viscosity is proposed, which takes into account the sizes of nanofiller aggregates and their surface structure. This model shows a good agreement with experimental data. It demonstrates a fundamental difference in the behavior of melt viscosity for polymer micro- and nanocomposites.

聚丙烯/球状碳纳米复合材料熔体粘度的分形处理

摘要

结果表明，为聚合物微复合材料制定的理论模型不能描述聚丙烯/球状碳纳米复合材料在纳米填料含量变化时熔体粘度的变化。然后提出了粘度的分形模型，该模型考虑了纳米填料聚集体的尺寸及其表面结构。该模型与实验数据显示出良好的一致性。它证明了聚合物微米和纳米复合材料的熔体粘度行为的根本差异。
