摘要：

Alignment of single-walled carbon nanotubes in a bulk epoxy matrix (see Figure) has been achieved through the processing of the composite inside a high magnetic field (15-25 T). The self-organization of the epoxy chains inside the magnetic field mediated the reorientation process of the single-walled carbon nanotubes. The alignment becomes more pronounced as a function of the magnetic field strength.
