SYNTHESIS OF HYBRID POLYMERIC NANOCOMPOUNDS BY MICROWAVE RADIATION:POLYMERIZATION IN SITU OF NYLON-6 AND CARBON NANOTUBES OF MULTIPLE WALLS.

摘要

The present invention is a novel process for the manufacture and synthesis of hybrid polymeric nanocompounds, these nanomaterials being obtained by the process of polymerization in situ assisted by microwaves and being characterized in that it uses pure or unfunctionalized nanoparticles. The present process allows electric power to be saved since it reduces the consumption in an 86% during the synthesis of these hybrid polymeric nanocompounds. The materials obtained during the processes present an interfacial adhesion and dispersion degree between the nanoparticles and the polymer, which is able to promote the transference of properties from the nanoparticles to the polymer such as the electric conductivity that is increased in up to 10 orders of magnitude of 4.76 x10-15 to 3.13 x 10-5; in such a manner the nanoparticles has a significant effect on the crystalline behaviour of Nylon-6 since the crystallisation temperature thereof is increased and a second peak generated. The nanohybri ds of MWCNT-Nylon6 have the property of forming films with a conductivity of 3.4 x 10-1 Siemens, which is close to the conductivity of 1.4 Siemens, thus being applied as materials for conducting the electricity.
