Polystyrene carbon nanotube nanocomposites

Carbon nanotubes (CNTs) exhibit excellent mechanical, electrical, and magnetic properties as well as nanometer-scale diameter and high aspect ratio, which give them a great deal of attention and have been the focus of extensive research efforts as model systems in nanotechnology. Since CNTs usually agglomerate due to van der Waals forces, it is extremely difficult to disperse and align them in a polymer matrix, which consequently leading to many defect sites in the composites and limiting the efficiency of CNTs on polymer matrices. In this chapter, we focus on recent development in preparation and characterization and also review effective parameters on CNT dispersion in polystyrene carbon nanotube nanocomposites
