本文对碳纳米管（CNT）/丙烯腈-丁二烯-苯乙烯（ABS）纳米复合材料的微观结构和力学性能进行了实验和理论分析。此外，纳米复合材料的热降解行为作为功能的碳纳米管进行了研究。CNT/ABS纳米复合材料填充高达10重量%的CNT制备通过熔融混合，然后通过压缩成型。由于CNT和ABS基体的苯乙烯-丙烯腈（SAN）部分之间的相容性，观察到在CNT/SAN界面处具有良好界面粘附性的优异分散性。发现这种微结构显著提高了纳米复合材料的拉伸强度和杨氏模量。体积排阻电逾渗模型和考克斯拉伸模量模型均预期熔融混合后纳米填料的纵横比为约80。该值与文献中相同类型纳米管的实验测量值一致。(C)2016爱思唯尔有限公司版权所有
In this work, experimental and theoretical analysis of the microstructure and mechanical properties of carbon nanotube (CNT)/Acrylonitrile-butadiene-styrene (ABS) nanocomposite were conducted. In addition, the thermal degradation behavior of the nanocomposite as function of CNT was investigated. CNT/ABS nanocomposites filled with up to 10 wt% CNT were prepared by melt mixing followed by compression molding. Due to the compatibility between the CNT and the styrene-acrylonitrile (SAN) part of the ABS matrix, excellent dispersion with good interfacial adhesion at the CNT/SAN interface was observed. This microstructure was found to significantly improve the nanocomposites' tensile strength and Young's modulus. Both the volume exclusion electrical percolation model and the Cox tensile modulus model expected that the aspect ratio of the nanofiller after melt mixing is about 80. This value is consistent with the experimentally measured value for the same type of nanotubes in literature. (C) 2016 Elsevier Ltd. All rights reserved.
