Abstract
The behaviour of fullerenes (mostly the C60 and C70) in a radical polymerization and during thermal/thermo-oxidative degradation of polymers is considered. The analysis of literature material clearly shows that fullerenes preferably act as scavengers of carbon-centered free radicals, and therefore they appear to be inhibitors for the radical polymerization and stabilizers for polymer materials.
No distinct indication of any proved active or specific role for oxygen-centered radicals has been specified.
As carbon nanotubes (CNTs) have electron affinities similar to those of fullerenes, and might therefore also be predicted to behave as radical traps in chain reactions such as polymerization and thermal degradation of polymers as well.
Kurzfassung
Das Verhalten von Fullerenen (hier vor allem C60– und C70–Fulleren) bei einer radikalischen Polymerisation und das der entsprechenden Polymere beim thermoxidativen Abbau werden untersucht. Aus der Literatur ist bekannt, dass Fullerene als C-Radikalfänger wirken. Deshalb wirken sie als Inhibitoren bei der radikalischen Polymerisation und als Stabilisatoren bei der Alterung von Polymeren. O-Radikale scheinen durch die Fullerene hingegen nicht beeinflusst zu werden. Kohlenstoff-Nanotubes haben eine ähnliche Elektronenaffinität wie die Fullerene, weshalb sie ebenfalls als Inhibitoren bzw. Stabilisatoren bei der radikalischen Polymerisation und dem thermoxidativen Abbau wirken.
