EXPERIMENTAL CORRELATION BETWEEN THE PROCESSING PARAMETER AND DIELECTRIC MATERIALS AND THERMAL CONDUCTIVITY OF EPOXY-CARBON NANOTUBE DECORATED WITH CACO3 DERIVED FROM WASTE EGGSHELL.

High thermal conductivity and dielectric materials with enhanced electrical conductivity are needed in advanced electronics. However, simultaneous improvement in this material remains a challenge. Here, the synergistic effect of dielectric materials and the high thermal conductivity of epoxy-carbon nanotube decorated with waste eggshell through the Taguchi-Grey experiment have been studied to achieve this challenge. The composite was produced by the solution stirring method. The dielectric constant, thermal and electrical conductivity, and morphology of the samples were evaluated. The optimal condition of the composite for higher electrical and thermal conductivity was obtained at 1wt%ESp, 2.5wt%CNTs, 90oC curing temperature, and 6 hours of curing time with 19,130% and 94.27% increments in thermal and electrical conductivity. The predicted grey relational grade was close to the experimental grey relational grade at a confidence limit of 95%. This validated the efficacy of the obtained optimal processing parameters. It was established that waste eggshells can be used to ensure good dispersion of CNTs for the production of conductive polymers for improved electrical and thermal conductivity. [ABSTRACT FROM AUTHOR]
