Abstract

We consider physical foundations for the realization of high-modulus and high-strength polymer/carbon nanotube nanocomposites with mechanical characteristics comparable with those for steel. We have determined two main factors that make it possible to obtain such nanocomposites, i.e., the structure of the nanofiller in the polymer matrix and a quite high concentration of the nanofiller. The fractal dimension of such a structure must be close to that of the surrounding Euclidian space (i.e., 3). It is shown that additional stretching of the nanocomposite gives two positive effects: the reduction of waviness of carbon nanotubes and the increase of the elastic modulus of the polymer matrix due to alignment of its macromolecules.

获得高模量聚合物/碳纳米管纳米复合材料的条件

摘要

我们认为物理基础可实现具有与钢相当的机械特性的高模量和高强度聚合物/碳纳米管纳米复合材料。我们已经确定了两个可能获得这种纳米复合材料的主要因素,即聚合物基质中纳米填料的结构和相当高浓度的纳米填料。这种结构的分形维数必须接近周围的欧几里德空间的分维数(即3)。结果表明,纳米复合材料的额外拉伸产生了两个积极的效果:碳纳米管的波纹度降低以及由于高分子大分子的排列而增加了聚合物基质的弹性模量。
