In this paper, we investigate the adhesion energy at the interface between single wall carbon nanotubes and polyethylene matrix with and without an external magnetic field. The carbon nanotubes are of two different chiralities — armchair (10,10), and zigzag (10,0), and the external high magnetic field is of 25 Tesla intensity. The study employs molecular dynamics simulations and concludes that the magnetic field decreases the interfacial adhesion energy although it increases the individual potential energies of the nanotubes, the polyethylene, and the composite.

Scattering Factor

The ability to align single wall carbon nanotubes (SWNTs) is paramount for harnessing their remarkable anisotropic electronic and mechanical properties. D.A. Walters et al. (Rice Univ.) have succeeded in aligning milligram quantities of SWNTs using a strong magnetic field. The nanotubes were aligned in suspension and simultaneously filtered to produce a thin membrane. However, small angle X-ray scattering (SAXS) — the traditional technique for obtaining fiber patterns — has proven ineffective in determining the degree of alignment due in part to carbon's weak atomic scattering factor for X-rays.In the present work we succeed in quantitatively characterizing this membrane using transmission electron microscopy (TEM). A self-supporting sample was prepared by peeling ∼ 0.5 mm long strips from the material. TEM images reveal that the membrane itself is not a single, large bundle (i.e. rope) of SWNTs. Instead, it has a prominent texture, corresponding to many ropes aligned parallel to the direction of the applied magnetic field.
