文摘

Thermal stability of a polymer: fullerne blend is increased using electron irradiation. Using in-situ transmission electron microscopy the nanostructure is studied. Electron irradiation stops phase separation between the polymer and fullerene. Electron irradiation quenches the formation and nucleation of fullerene crystals.
