Abstract
sol-gel transition include the following: the dynamic modulus data exhibited excellent TTS (gelling time/relaxation time superposition) as previously observed for weakly attractive colloidal gels. Three yield points were noticed for the final gel sample, suggested to mark the bond breaking of the cluster network, cage breaking of the resulting jammed flocculates, and, eventually, breakup of a flocculate into smaller agglomerates with increasing stress amplitude.
