Artigo Completo:

Carbon nanotubes (CNTs) were treated using acids and Hexamethylenediamine (HMDA). The presence of acid and amine chemical groups on the CNTs surface was confirmed by X-ray Photoeletron Spectroscopy (XPS). The nanocomposites were produced with epoxy resin and modified CNTs. Vickers hardness tests were carried out on the composites and neat resin. Results showed an increase in the sample hardness prepared with functionalized CNTs. This phenomenon is due to the compatibility between modified CNTs and epoxy resin is much higher than between bare CNTs and epoxy resin. This higher compatibility is related to the strong interfacial interaction between the functionalized CNTs and the polymer.
