N2 - The ability of epoxy composites to provide both high toughness and outstanding electrical conductivity is critical in several technical applications such as boards, electronic devices, anti-static electricity, and electromagnetic shielding. However, it was difficult to obtain the high toughness and electrical conductivity of conducting polymer to suit this purpose. Hence, this work will investigate the fracture toughness and electrical conductivity of epoxy/carbon nanotube surfaces coated with CaCO3 derived from waste eggshell (CNTs/CaCO3-ESp) for high toughness and electrical conductivity. The CNTs/CaCO3-ESp was produced by growing CNTs on CaCO3-ESp through a chemical hybridization process. The CNTs were firmly attached to the CaCO3-ESp and enhanced the dispersion of CNTs in the epoxy matrix. The electrical conductivity and fracture toughness of the epoxy/1.5wt% CaCO3-ESp-CNTs were improved by 235,789% and 6.51%, respectively. The fracture surface shows homogenous dispersion of CaCO3-ESp-CNTs in the epoxy matrix. It was found that used eggshells can be used to change CNTs so that they can be used to make epoxy composites with better strength and electrical conductivity for the electronics industry.
