UV-Vis diagnostics of the PMMA - C60 composite system and the kinetics of its thermal decomposition
Abstract
The influence of polymer-fullerene interactions and fullerene aggregation on the thermal stability of polymethylmethacrylate-fullerene C60 nanocomposite has been studied by means of thermal desorption mass-spectrometry and the UV-Vis absorption spectroscopy.
