Interfacial smoothening of polymer multilayers with molecules: a new approach in growing supramolecular layer structures

摘要: The development of polymer-based structures is hindered due to the difficulties in realizing well-defined modulated without interpenetration charged polymers. Two types polyelectrolyte multilayer structures, with and embedded layers biomolecule, glutamic acid, are compared using infrared spectroscopy X-ray neutron scattering techniques. Structure characterization multilayers focuses usually on arrangement along surface normal. Using specular off-specular we get insight into in- out-of-plane structure. A formation well-defined, smooth observed structure containing biomolecule. This reduced roughness associated a drastic decrease chain mobility responsible for interpenetration. In contrast, biomolecule forms an island-like Thus biomolecules can interrupt propagation at such interfaces which be effectively used achieving supramolecular layer out
