Abstract

original image

Magnetische Nanohohlkugeln aus Fe3O4 und einem Polymer (siehe Bild) wurden erhalten, indem Fe3O4-Nanopartikel zu einer Lösung von Polymer-Monomer-Paaren gegeben wurden, die aus einem kationischen Polymer (Chitosan) und einem anionischen Monomer (Acrylsäure) bestanden. Anschließend wurde die Acrylsäure polymerisiert, und nach der Polymerisation wurde das Chitosan selektiv vernetzt.
