Graphical Abstract

Nanopartikuläre Blockcopolymere bilden neuartige phasengetrennte Formen, deren Entstehung auf einem strukturfrustrierenden Begrenzungseffekt der Partikel beruht. Während Filme des Blockcopolymers lamellare Strukturen einnehmen, bilden die Nanopartikel spezielle Morphologien (ball-, pilz-, rad- und schraubenförmige sowie Janus-Strukturen), je nach Verhältnis von Partikeldurchmesser und Molekulargewicht des Polymers.
