Effect of Various Carbon Nanotubes Contents on Surface Resistance and Thermal Degradation of Polypropylene/ Polyamide 6/Glass Fiber Composite

Abstract

The composite samples containing commercially available carbon nanotubes (CNTs), polypropylene (PP), polyamide 6/glass fiber composite (PA6/GF, 50%/50%) were prepared. They were (x%CNTs)/PP/(PA6/GF) (x/80/20, x% is the percentage of CNTs in the obtained composites, where x=0, 1, 2, 3, 4, 5, 6, respectively.). PA6/GF (50%/50%) and PP samples were also made as control. Surface resistance and thermal degradation for all the samples were measured. According to the resulting data, it is found that, with the increasing of carbon nanotubes contents, the surface resistance for the composite samples decreased, while the initial decomposition temperature increased. The result may be helpful to choose proper carbon nanotubes contents for antistatic and anti-degradation polymeric materials.
