A simple, fast, and cost-effective method to fabricate conductive paths on insulating Ag-containing polyamide 6 (PA6) composites by laser beam treatment is presented in this study. First, Ag-hybrid microparticles (Ag-MP) with a total metal load of up 19 wt% are synthesized based reactive encapsulation strategy utilizing activated anionic polymerization ε-caprolactam solution, the presence Ag na...
