Experimental study of fullerene-PVP polymers by small-angle neutron scattering

Small_angle neutron scattering technique is employed to investigate the structure of fullerene-PVP polymers and the variation of their size with fullerene content. The results indicate that the relative lengths of both mono-molecule and mac romolecule chains in solution with fullerene are shorter than those in pure PVP solution, and the volumes of fullerene-PVP polymers in solution with high fullerene content become much smaller.
