摘要：

We briefly reviewed the historical research on VR colloids, and its impact on VR upgrading. We then reported our study of VR/solvent systems, in which we (1) directly characterized the self-association phenomenon of VR molecules, (2) explicitly determined the colloidal structure and quantitatively estimated the colloid-solvent interaction, (3) determined the detailed particle shape, polydispersity, and the surface roughness, (4) identified the type of intermolecular interaction, which is responsible for self-associations, and (5) characterized the colloidal dynamics and their slowing down, as a function of concentration and temperature.
