摘要
我们研究了分散在其中的碳纳米管的向列液晶驱动排列。我们扩展了(P. Van der Schoot et al. 2008, V. Popa-Nita, and S. Kralj 2010)中提出的介观模型，包括碳纳米管长度和密度的影响。混合物的自由能表示为两种碳纳米管类型的溶向列有序的Doi自由能、液晶的热向列有序的Landau-de Gennes自由能和液晶分子与碳纳米管之间的耦合项之和。分析了混合物的相序与体积分数、耦合强度和温度的关系。
Length Bidisperse Carbon Nanotubes Dispersions in Thermotropic Liquid Crystals
We study nematic liquid crystal driven alignment of carbon nanotubes dispersed in them. We extend the mesoscopic model presented in (P. Van der Schoot et al. 2008, V. Popa-Nita, and S. Kralj 2010) including the effect of length bidispersity of carbon nanotubes. The free energy of the mixture is written as the sum of the Doi free energy for lyotropic nematic ordering of the two carbon nanotubes types, the Landau-de Gennes free energy for the thermotropic ordering of liquid crystal, and the coupling term between liquid crystal molecules and carbon nanotubes. The phase ordering of the mixtures is analyzed as a function of volume fraction, the strength of coupling, and the temperature.
