Molecular diffusion and permeability decrease with increasing nanoparticle size, concentration, and polymer length due to steric hindrance and reduced polymer flexibility. Shorter polymers facilitate faster transport, while longer chains slow diffusion. In contrast, electrical conductivity rises with nanoparticle number, as nanoparticles form conductive pathways, with medium-length polymers showing optimal performance. These results highlight that nanoparticle crowding dominates molecular transport, whereas nanoparticle addition enhances electrical conduction, providing insight for designing polymer–nanoparticle composites with tailored transport properties Full Text Additional Declarations No competing interests reported.
