Since their discovery in 1991, carbon nanotubes have generated huge activity in most areas of science and engineering due to their unprecedented physical and chemical properties. No previous material has displayed the combination of superlative mechanical, thermal and electronic properties attributed to them. These properties make nanotubes ideal, not only for a wide range of applications but as a test bed for fundamental science.
CNTs are considered to be the most promising candidates as ideal reinforcing fillers in high strength, light weight polymer nanocomposites due to their low density, high aspect ratio and exceptional mechanical properties (such as extremely high moduli and stiffness).
I have recently read an article on CNT based composites entitled “The thermal and mechanical properties of a polyurethane/multi-walled carbonnanotube composite”, published in Carbon. The thermal and mechanical properties of a polyurethane/multi-walled carbon nanotube composite were characterized by dynamic mechanical thermal analysis, thermogravimetric analysis and tensile testing.
