✦ Synopsis

Electrospun nanofibers of polyacrylonitrile, containing an iron compound, have been converted to carbon nanofibers, with iron particles on their surfaces. The iron particles catalyze the growth of carbon nanotubes with iron tips (see Figure). A mechanically strong and electrically conducting path exists between each metal particle and the supporting nanofiber network, which extends to macroscopic dimensions.

## Abstract We examined electrical properties of composites of carbon nanofibers (CNFs)/linear low‐density polyethylene (LLDPE) in the range of mixing time. An addition of CNFs into LLDPE led to a decrease of electrical resistivity, and the large amounts of CNFs were required to reach the electrica
