    • The invention relates to a method for preparing a solution of micelles in an organic medium, which micelles comprise nanoparticles stabilized by a shell of at least one polymer having a terminal anchoring group which exhibits a high affinity to the surface of the nanoparticles. In a preferred embodiment, said method comprises at least the following steps: i) providing an aqueous solution/dispersion of nanoparticles, in particular metal or metal oxide nanoparticles, stabilized by a shell of a first stabilizing agent; ii) optionally displacing the molecules of the first stabilizing agent by molecules of a second stabilizing agent; iii) transferring the stabilized nanoparticles obtained in step i) or ii) into a solution/dispersion of anchoring group-terminated polymer in an unpolar organic solvent; iv) displacing the molecules of the first or second stabilizing agent by anchoring group-terminated polymer molecules having a higher affinity to the nanoparticles than the molecules of the first or second stabilizing agent; v) separating the polymer-stabilized nanoparticles from unbound polymer. Further aspects of the invention relate to the nanostructured substrate surfaces obtainable by said method as well as to the uses thereof.
    • 本发明涉及一种在有机介质中制备胶束溶液的方法,该胶束包含由具有至少一种具有对纳米颗粒表面具有高亲和力的末端锚定基团的聚合物壳体稳定的纳米颗粒。 在优选的实施方案中,所述方法包括至少以下步骤:i)提供由第一稳定剂的壳稳定的纳米颗粒的水溶液/分散体,特别是金属或金属氧化物纳米颗粒; ii)任选地通过第二稳定剂的分子置换第一稳定剂的分子; iii)将在步骤i)或ii)中获得的稳定的纳米颗粒转移到非极性有机溶剂中的锚定基团封端的聚合物的溶液/分散体; iv)通过锚定具有比第一或第二稳定剂的分子对纳米颗粒更高亲和力的基团封端的聚合物分子来置换第一或第二稳定剂的分子; v)将聚合物稳定的纳米颗粒与未结合的聚合物分离。 本发明的其它方面涉及通过所述方法可获得的纳米结构化基材表面及其用途。
