Wir stellen eine auf Goldnanostäbchen (AuNR) basierende Methode vor, um eine radikalische Polymerisation in Wasser mit Nahinfrarotlicht (800 nm) zu induzieren. Der Prozess nutzt die photothermische Umwandlung in AuNR und die anschließende Wärmeübertragung auf einen Radikalinitiator (hier Azobisisobutyronitril) für die primäre Radikalbildung. Es wurde ein breites Spektrum an Reaktionsbedingungen untersucht,...
We introduce a gold nanorod (AuNR) driven methodology to induce free radical polymerization in water with near infrared light (800 nm). The process exploits photothermal conversion in AuNR and subsequent heat transfer to a radical initiator (here azobisisobutyronitrile) for primary radical generation. A broad range of reaction conditions were investigated, demonstrating control over molecular weight...
