利用原子力显微镜在纳米尺度上进行了拔出实验，以评估多壁碳纳米管与聚乙烯-丁烯基质之间的界面粘附性。根据测量的拔出力和嵌入长度计算了纳米管聚合物界面的断裂能。结果表明，存在较强的界面，较小直径的纳米管具有较高的断裂能。(C)2004爱思唯尔有限公司。保留所有权利。
Pullout experiments were performed at the nanoscale using an atomic force microscope, to assess the interfacial adhesion between multi-walled carbon nanotubes and a matrix of polyethylene-butene. Fracture energy for the nanotube polymer interface was calculated from the measured pullout forces and embedded lengths. The results suggest the existence of a relatively strong interface, with higher fracture energy for smaller diameter nanotubes. (C) 2004 Elsevier Ltd. All rights reserved.
