Small-angle neutron scattering by liquid systems of fullerenes С60 and С70

Abstract

Results of studies of the cluster state of fullerenes C60 and C70 in a solution of toluene with acetonitrile, performed by small-angle neutron scattering are presented. The experiment has been carried out using the small-angle scattering spectrometer YuMO, located at the IBR-2 reactor of the Joint Institute for Nuclear Research (Dubna). It has shown that a content of acetonitrile in the solution is increased, the agglomerated fraction was increasing. Sharp tendency to aggregation was observed after the certain threshold value of acetonitrile concentration was exceeded. The processes of C60 and C70 fullerenes’ cluster formation were analyzed in comparison.
