How Does Nanotechnology Enhance Barrier Properties?
Nanomaterials have unique structural characteristics that contribute to superior barrier properties. When materials are reduced to the nanoscale, their surface area to volume ratio increases, creating more interaction sites and reducing the permeability of substances through the material. For instance, the incorporation of graphene nanosheets into polymer matrices can significantly improve the barrier properties by creating a tortuous path for molecules to traverse, thereby enhancing the material's resistance to gases and liquids.
