Here, we introduce a general and versatile approach for preparing the functional nanocomposite multilayers with unprecedented unique properties via the consecutive adsorption of hydrophobic metal or metal oxide NPs and electrostatically charged components onto substrates. The strategy, amphiphilic LbL assembly using sulfonic acid (SO3–)–functionalized components, is based on the ligand exchange between the stabilizers of hydrophobic NPs in nonpolar solvent and the SO3– groups of PEs in aqueous solution. Our approach highlights the fact that a variety of functional components, ranging from water-soluble/dispersible materials to hydrophobic NPs can be easily and directly incorporated within multilayer films without additional surface modification of pristine NPs or the insertion of additional polymer layers. |
