Аннотация: In the present work, we offer a novel view on description of equilibrium distributed aggregates for a special but often met in practice case of strongly aggregating nanoparticles (NP) in solution resulting in broad distribution of aggregates by dimension. We suggest, that the experimental aggregates distributions measured by conventional methods (such as light scattering, trajectory analysis, probe/electronic microscopies) may be clustered into three groups differed by the underlying thermodynamic mechanism of aggregates formation, viz. Type A (classical ‘isodesmic’ sequential addition of monomers, resulting in dynamic equilibrium formed between the processes of formation/disruption of various aggregates), Type B (kinetically-arrested state of aggregates stabilized by a balance of internal/interfacial interactions) and Type C (a hybrid of Type A and Type B). Based on these considerations and using the aggregation data for the test NPs, viz. aromatic molecules (Type A), nanodiamonds (Type B) and fullerenes (Type C), we derived general analytical equations for description of experimental aggregates distributions for each type of NPs aggregation.
