摘要：

Propylene-oxide oligomers in heavy water (their molecular mass is ∼500, and the concentration C varies from ∼0.6 to 5.0 g/dL) and similar systems with C60 and C70 fullerenes and C60(OH)x fullerenols (x ∼ 20), i.e., functionalized oligopropylene oxides, are studied via small-angle neutron scattering. The initial oligomers are found to create spherical micelles (∼40 molecules) in the solution. It is ascertained that, in oligopropylene-oxide solutions, the C60, C70, and C60(OH)x derivatives (∼1 wt % of fullerene relative to the oligomer) modify its molecular organization, acting as physical bonds whereby micelles are joined into large-scale linear, twisted, and branched chain superstructures. © 2014, Pleiades Publishing, Ltd.
