Abstract

Unpurified carbon nanotubes exhibit enhanced electromagnetic absorption at radiofrequencies and the underlying mechanism involves the polarization of odd alternate π-radicals encapsulated in carbonaceous impurities. The intertube junctions behave as capacitive elements and are found capable of absorbing radiation in the low frequency domain.
