Abstract This study investigates the incorporation of nano‐silver carbon black (AgCB) into polypropylene (PP) to develop nanocomposites with enhanced mechanical, thermal, barrier, and antibacterial properties. AgCB, synthesized a black‐to‐silver ratio 19:1, was incorporated PP at 0.5–5 wt% via melt blending. At 1 wt%, AgCB improved tensile strength by 21.5%, thermal stability, reduced water vapor oxygen permeability, achieving optimal performance uniform dispersion. With increasing content, activity significantly, sterilization rate exceeding 99.7%, although higher concentrations led agglomeration, reducing mechanical barrier performance. The dual function as nucleating agent functional additive demonstrated through DSC, WAXRD, tests. work highlights potential cost‐effective filler for composites, suitable applications requiring durability, properties, antimicrobial efficacy. Highlights Nano‐silver improves crystallinity Optimal enhances PP's stability. creates tortuous pathways, permeability. Low‐cost (CB:Ag = 19:1) achieves strong (>99% efficacy). mitigates nanoparticle enhancing dispersion in PP.
