Structural organization of colloidal solution of fullerene C60 in water by data of small angle neutron scattering

In the present work results of analysis of SANS experimental curves for fullerene C60 water dispersions obtained without direct chemical modification and addition of stabilizers are presented. Simulation with the use of the spherical particle model fails. Introduction of the particle anisotropy parameter allows simulations of experimental curves with small number of parameters. Exponential and log-normal size distributions fit the simulation procedure. A number of structural models of the colloidal particle are considered. Possible types of the structural organization of investigated colloidal solutions are discussed.
