Abstract The present study presents a novel method for preparing multi‐walled carbon nanotubes (MWCNTs) grafted with polyacrylicnitrile (PAN) through the process of plasma‐induced grafting polymerization. After the plasma grafting process, the MWCNTs were converted into acrylicnitrile modified CNTs (MWCNTs‐ g ‐AN), which in reaction with hydroxylamine produced the aminated CNTs (MWCNTs ‐g‐ mAN). After the plasma modification process, X‐ray photoelectron spectroscopes (XPSs) of a high resolution were used to characterize the functional groups on the surface of the MWCNTs. In addition, observing the transmission electron microscopy (TEM) image reveals that a uniform polymer layer is grafted onto the surface of the MWCNTs and the functionalized CNTs showed a better dispersion than the pristine MWCNTs in epoxy resin. Moreover, the addition of a small quantity of the MWCNTs ‐g‐ mAN to the nanocomposites showed noticeable enhancements in their electrical conductivity. magnified image
