Steel/Polymer Composites (SPCs) represent a promising class of materials that combine the strengths of steel and polymers, making them ideal candidates for various structural applications. Achieving robust interfacial adhesion between steel and polymer, while maintaining electrical conductivity for welding, presents a significant challenge in SPC development. In order to enable spot welding of these SPCs, mechano-chemistry was employed to embed carbon-based graphitic materials within the plastic matrix, enhancing electrical conductivity. The selection of Polyketone as a core material facilitates the adsorption of conductive fillers, such as Carbon Nanotubes and Graphite Platelets. GNP-Polyketone, with smaller lateral dimensions (50 ~ 100 nm), exhibits the highest electrical conductivity of 207.5 S/cm. Scanning Electron Microscopy confirms effective filler adsorption without pre-treatment
