The last decade has witnessed enormous improvement in the area of nanofillers on electrical, thermal and mechanical properties of polymeric materials. The dielectric and thermal properties of standard enamel and various nanofiller mixed enamel were detailed and analyzed. Nanopowders of ZrO2, Al2O3, CNT and ZnO were used as filler. Ball mill method was used to synthesize various nanofillers such as ZrO2, Al2O3 and ZnO. CNT were synthesized by the process called chemical vapour deposition (CVD). The basic dielectric properties such as dielectric strength and partial discharge characteristics of the enamel filled with various nanofillers such as ZrO2, Al2O3, CNT and ZnO at various proportions (1%, 3% and 5%) were analyzed and compared with the properties of the standard enamel. The experimental results show that enamel mixed with nanofillers has higher dielectric properties when compared to that of standard enamel.
