Abstract: Electronic based industry has become one of the highest growth industries in the world, which electrostatic discharge (ESD) could be a serious problem associated for a specific application. Due to the low price and availability of pristine graphite in large quantities, graphene nanoplatelets (GNPs) is considered an ideal choice as conductive fillers to replace carbon nanotube (CNTs) or mix them to produce hybrid conductive fillers. Accordingly, this report was focused on using suitable oxygen-gas modified hybrid fillers in amorphous Acrylonitrile-Butadiene-Styrene (ABS) and semi-crystalline polypropylene (PP), which they are mainly used for electronic packaging. Nanocomposites were successfully prepared using a twin-screw extruder, which ABS/nanofiller or PP/nanofiller masterbatch was mixed with neat polymer to the desired concentrations of nanofillers (2, 4, 6, and 8 wt%). Based on static dissipative range of surface electrical resistivity, the suitable ratio of nanofiller (80:20 of O2-CNTs:O2-GNPs) and critical amount of nanofiller loading on mechanical properties was found to be 2.0 wt%. ABS reinforced with 2.0 wt% of nanofiller resulted in an increase of Young’s modulus 27% and of tensile strength 24%, with a reduction of elongation at break 75%. PP reinforced with 2.0 wt% of nanofiller resulted in an increase of Young’s modulus 12% and of tensile strength 6%, with a reduction of elongation at break 71%. The surface electrical resistivity and thermal conductivity of nanocomposites were sharply decreased from 1016 to 106 ohm/square and increased from 0.208 to 0.349 W/m.K, respectively, which could be designated as a static dissipative material
