Characterization of Electrical and Thermal Properties of Enamel Filled with Carbon Nanotubes

摘要

The last decade has witnessed significant developments in the area of nanoparticles and nanoscale fillers on electrical, thermal and mechanical properties of polymeric materials. The dielectric and thermal properties of standard (Poly amide-imide) and nanoscale filled samples were detailed and analyzed. Carbon nanotubes have been tested as filler. Carbon nanotubes were synthesized by the process called chemical vapour deposition (CVD). The basic properties such as dielectric loss tangent (tanδ), dielectric constant(ε), dielectric strength, partial dis charge inception voltage, surface resistivity, quality factor, phase angle, dielectric conductivity, dielectric power loss and thermal withstand strength of the enamel filled with carbon nanotubes were analyzed and compared with the properties of the standard enamel. The experimental results show that there was a significant improvement in the properties of the enamel by the addition of carbon nanotubes.
