Description
Summary:The nanostructure materials are a prefer option to the high-growth technological changes. The remarkable nanotubes and other carbon nanostructure properties have been theoretically and experimentally tested. These nanostructures can be used as reinforcement materials in composites; the research main challenge is the dispersion of these carbon materials in different matrices caused by cluster formations produced by the intermolecular forces. The aim of this research was the synthesis and characterization of a composite material from carbon nanotubes and styrene oligomers with hydroxyl end groups; and the analysis of their dispersion and mechanical and electrical properties. Pristine and functionalized carbon nanotubes and polystyrene with hydroxyl end groups were synthesized; furthermore, magnetic field was applied to the composites to promote dispersion of carbon nanotubes. The materials were characterized by scanning electron microscopy, FTIR and Raman spectroscopy. The Raman spectroscopy has demonstrated interaction between carbon nanostructures and polymers; this changes their mechanical and electrical properties. The composites formed with functionalized carbon nanotubes (1.6 wt%) have the highest hardness value (91.16 HV), five times over the pristine polymer. As carbon nanostructure concentration increases, the composite acquires conductivity and the electron transport is promoted. The values obtained in the composites qualify them as electromagnetic interference shields, those demand materials with higher electrical conductivity than conventional polystyrene.
