Abstract:
The paper presents the results of studying the absorption spectra of polymer – fullerene Ñ$_{60}$ composites. In the polymethyl methacrylate – Ñ$_{60}$ composite, a gradual process of aggregation of fullerene is registered during heating. This made it possible to determine the diffusion coefficient of Ñ$_{60}$ molecules in this polymer. The difference in the absorption spectra of Ñ$_{60}$ clusters in different composites indicates the interaction of the clusters with the polymer matrix.
