Percolation of single-walled carbon nanotubes in ceramic matrix nanocomposites [PDF]
The percolation of carbon nanotubes (CNT) in an electrical insulating ceramic is studied for the first time. The in situ synthesis of the CNT (0.2–25 vol%) by a CCVD route allows to achieve their homogeneous distribution in the spinel matrix.
