Abstract
The present work deals with the development of solution-casted epoxy composites reinforced with B4C and PbO particles with an aim to examine its applicability to dielectric applications. The samples with different weight percentages of PbO were prepared as a hybridization with 20% B4C particles and are subjected to dielectric studies. The important properties such as dielectric constant, dielectric loss factor and AC conductivity of the samples as a function of different frequencies and temperatures were studied and reported in this article. The studies were conducted at five different frequencies ranging from 100 Hz to 1 MHz at different temperature range of 40ͦ C to 150ͦ C. The results showcased the enhancement of the properties upon the increase in addition of the PbO filler from 10wt.% to 40wt.%. The dielectric constant and the dielectric loss factor of the sample with 40 wt % of PbO were found to be 1.78 and 1.3 respectively at 100 Hz and the AC conductivity of the sample with 40wt % of PbO was found to be 998 × 10− 8 mho/m at 1 MHz.
