This work reports a statistical study on the relationship between the chemical–physical properties of CNTs, which vary by changing the conditions of purification and plasma treatment, and the macroscopic properties of PC‐based nanocomposites. CNTs are synthesized and then purified in two different ways and used as fillers for the preparation of PC/CNTs nanocomposites. In some cases, oxygen plasma treatment is carried out to improve their affinity to the matrix. The CNTs are characterized by TGA, ICP/OES, and FT‐Raman spectroscopy, titration and morphological analysis. Mechanical, dynamic‐mechanical, electrical, and morphological tests are used for characterizing PC/CNTs nanocomposites.
