Abstract 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 (Polyamide-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 (tand), dielectric constant(e), dielectric strength, partial discharge 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.

78.1 Introduction In the last few years, a great deal of attention has been given to the application of nanodielectrics in the field of electrical insulating materials. It has been reported that the use of nano particles in the matrix of polymeric materials can greatly improve the thermal, mechanical and electrical properties of polymeric nanocomposites [1]. Insulating materials play a significant role in the design and performance of high voltage systems. They can be used for insulation purposes, cooling purposes and mechanical support [2]. Despite the basic understanding of electrical breakdown of materials, electrical surface flashover phenomena, physical mechanisms responsible for the initiation of such unwanted electrical activities within an insulation system composed of such advanced materials must be investigated before they can be commercially available [3]. The findings of such studies were essential for the development of nano-electric and other advanced materials and the techniques to predict the reliability of the advanced electrical systems which utilize these materials. The nanostructured polymeric materials are object of great interest by the researchers.
