What You Need to Know
Silver nanoparticles release Ag⁺ ions that disrupt bacterial cell membranes, while zinc oxide nanoparticles absorb UV radiation and generate reactive oxygen species that inhibit oxidation. Graphene oxide layers create a tortuous path for gas molecules, reducing oxygen transmission. The effectiveness depends on particle size, loading, and polymer matrix interactions.
