Abstract

Polypropylene/ nano-copper composites have been prepared with 0.5, 1, 1.5 and 2.5 wt.% nano-copper particles by mixing the nano-copper physically with the polypropylene granules then extruded by a twin screw extruder. A comprehensive study on these composites was conducted by measuring the material relative permittivity, electrical conductivity, thermal properties and tensile strength. The results showed a significant enhancement of the composite behavior up to 1.5 wt.% nano-particles addition. The increase of the nanoparticles up to 1.5 wt.% Cu decreases the relative permittivity and slightly increases the electrical conductivity. Finally, the fabricated composites with different nano-copper contents have large findings within different applications especially in electronics, packaging, and environmental issues.
