Abstract

The aggregation of dense colloidal solutions has been investigated by means of low-angle static light scattering. We show that the scattered pattern exhibits a finite-q-vector peak, whose intensity and position q₌ change with time. We find that the intensity distributions scale according to S (q/q₌, t) =q₌ (t) ^-dF (q/q₌), in agreement with the scaling law for spinodal decomposition. While d=3 for spinodal decomposition, here scaling requires that d=d₅, the fractal dimension of the clusters.
