Letter

The use of carbon nanotubes (CNTs) as fiber reinforcement in polymer matrix composites is currently being investigated because of their superior mechanical, electrical, and thermal properties [1]. However, recent research has raised some concerns that the widespread use of CNTs may lead to mesothelioma, cancer of the lining of the lungs, just like asbestos [2]. During the machining of the CNT-reinforced composites, CNTs may be pulled out of the polymer matrix and spewed into the air, where they present health risks. To ensure safety in using and manufacturing CNT-based products, a detailed understanding of the CNT pullout from a polymer matrix is essential.

The CNT pullout from a polymer matrix has been investigated with classical molecular dynamics simulations [3, 4, 5]. In addition to the nonbonded van der Waals interaction, the chemical bond (i.e., cross-link) between CNT and polymer matrix plays an important role in the pullout [5]. The pullout at nanoscale levels exhibits an...
