Analysis of Thermal and Electrical Properties of Enamel Filled with Various Nanofillers Such as ZrO2, Al2O3 and CNT

The last decade has witnessed significant 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 and CNT were used as filler. Ball Mill was used to synthesize nanofillers of ZrO₂ and Al₂O₃. CNT were synthesized by the process called chemical vapour deposition (CVD). The basic dielectric properties such as dielectric strength, partial discharge characteristics and thermal withstand strength of the enamel filled with various nanofillers such as ZrO₂, Al₂O₃ and CNT 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 various nanofillers has higher thermal properties when compared to that of standard enamel.
