This work presents diverse results which depend on different parameters that play an important role in the distribution, interaction and synergetic effect in composites developed with the incorporation of multiwalled nanotubes in different polymeric matrix. The nanocomposites evaluated were made by a variety of processing approaches with the assistance of additives and ultrasound. In addition is presented a chemical modification of these carbon structures in the surface and tips, showing that it is possible take advantage of the physical-chemical changes produced in the nanotubes when new moieties are attached in order to develop new polymeric nanocomposites with outstanding mechanical and thermal properties.The interaction has been evaluated in our work, improving the thermal and mechanical properties, these results are compared with other obtained in different papers where chemical functionalization was developed with diverse results. Finally in this work are discussed the behavior and the results obtained in these materials when relatively high concentrations are incorporated in nanocomposites based carbon nanotubes, showing an interesting effect found in this and in other works.
