| Abstract: | The γ irradiation of polyisoprene and C60 solutions in decalin at 50, 100 and 150 kGy was employed to prepare polyisoprene/C60 nanocomposites. The nanocomposites were obtained as black gels. The excess of decalin was removed by treatment with methanol and acetone and the dried collapsed gels were studied by FT-IR spectroscopy and thermogravimetric analysis (TGA–DTG) and also by differential thermal analysis (DTA). The thermal stability was found to be enhanced by the presence of C60 fullerene and by the crosslinking density.For reference, also the radiolysis of C60 in decalin and the radiolysis of polyisoprene in decalin were studied. The data obtained were useful for the interpretation of the network structure of the polyisoprene/C60 nanocomposites and their thermal behaviour. |
