An easy and robust approach for the production of long‐term‐stable silver nanoparticle dispersions with narrow size distribution (mean diameter ≈3–5 nm) has been developed. Amphiphilic‐modified hyperbranched polyethyleneimines with core/shell architecture were used as macromolecular templates and carriers. We systematically investigated the antibacterial performance and morphology of thin silver‐loaded hyperbranched polymer coatings on poly(ethylene terephthalate) prepared by different wet coating techniques. Furthermore, the influence of the density of the hydrophobic shell, varied by the degree of amidation between 50 and 70%, was studied with respect to the silver release behavior, wetting properties and antibacterial activity of the silver/hbp hybrid surface coatings.

Cover: A new approach for the production of silver nanoparticles (AgNPs) using amphiphil-modified hyperbranched polyethyleneimines as templates and carriers is described. Dispersions of core-shell-type hbPEI/AgNP hybrids are used to prepare thin coating films to study the performance of polymeric surfaces with antibacterial properties. Further details can be found in the article by M. Gladitz,* S. Reinemann,* and H.-J. Radusch on page 178.
