Structure Transformation in Fullerenes C60 at High Temperature Treatment

The changes in the local structure of the fullerenes C60 are studied after high-temperature annealing. Based on the model of atomic configurations obtained by reverse Monte Carlo, the quantitative character-istics of the topological order are founded for the C60 in initial state and after annealing. It is shown that the critical temperature of the beginning of the destruction of the structure of molecular lattice of fuller-enes is 900° C (30 min). At this temperature, a partial breakage of the fullerene molecules occurs. At tem-perature of 1600° C, fully breakage of fullerene molecules and formation of amorphous carbon takes place.

Interaction of hydrogen with amorphous, nanostructured and fine crystalline functional materials

International audienceThe influence of hydrogen on the main characteristics of functional materials was investigated. Changes in the mechanical parameters were interpreted in terms of microstructure phase transitions
