11 reported that the Young's modulus and strength of the nanophased nylon 6 filaments increased by 220% and 164%, respectively with the addition of only 1 wt% MWCNTs.

10 Recently, the nylon 6 nanocomposites with carbon have been demonstrated to show excellent properties. Nylon is a well known engineering thermoplastic used in electric installation, transportation equipment, spinning and other aplications, because of its outstanding combination of good mechanical properties and easy process-ability. Therefore, the study on the influences of modified CNTs is important for the new applications of polymer/CNT composites. 9 reported that the mechanical properties and crystallization behavior of poly(ether ether ketone) (PEEK) are influenced by the modification of MWCNTs, and improved mechanical properties appear in the functionalized CNT/PEEK composites. Their results show that the storage modulus can increase with the addition of unfuntionalized MWCNTs, whereas a constant value or even a weak reduction was observed for functionalized nanotubes.

8 investigated the mechanical properties of epoxy composites altered by multi-wall carbon nanotubes (MWCNTs) modified with oxatyl. 7 reported that the characteristics of polymer/CNTs composites are mostly dependent on the polymers and the processing used to make the composites. 5,6 Therefore, it is necessary to pay attention to the suitable chemical or physical treatments that may lead to different surface morphologies of carbon nanotubes, which may improve their dispersion and adhesion in the polymer matrix. 2вЂ“4 The most relevant issues are to disperse CNTs well in polymer matrix and to create a strong interfacial binding between the polymer matrix and the CNTs. The properties of polymer/CNTs composites have been intensively investigated by experiments. 1 Of the carbon-based nanofillers, carbon nanotubes (CNTs) have attracted considerable attention due to their intrinsic mechanical and electrical properties, and thermal stability. Introduction Polymer/ nanoparticle interfaces play an important role in new applications involving hybrid materials, where nanoparticles are added to a polymer to alter its structural and mechanical properties without affecting the main chemical features of the supporting matrix. Therefore, the functionalized CNT can expand the application of polymer in actual production. Our calculational results show that the vdW interaction energies of all the functionalized CNT/ nylon 6 composites are close to that of the pristine CNT/ nylon 6 composite, implicating the electrostatic interactions are responsible for the strong IBE of the functionalized CNT/ nylon 6 composites. The non-bond energies from both vdW and electrostatic interactions, are calculated for nylon 6 and CNT functionalized by different groups. The properties of the nanocomposites are investigated with the IBE between CNT and nylon 6. Molecular dynamics simulations of nylon 6 melts and its composite with pristine CNT or functionalized CNT embedded have been performed.

The critical challenge for preparing carbon nanotube (CNT)/ polymer nanocomposites is how to create a strong interfacial binding energy (IBE) between the polymer matrix and the CNT.
