摘要
We present a study of the solute-solute interaction and solubility for C-60 in CS2 solution. We have evidenced and characterised, by a second virial coefficient A(2), an attractive C-60-C-60 interaction in CS2 by small-angle neutron scattering, We present results about the temperature dependence of the C-60 solubility in CS2 obtained with a static light-scattering technique, We have compared the dependence of the solubility versus solute-solute interaction for C-60 in CS2 to that of lysozyme in aqueous solutions, using the effective hard-sphere adhesive potential for the solute-solute interactions in both systems, This comparison between C-60, a simple model particle for short-range interactions, and other much more complex molecules like proteins shows the analogies between the two systems.
