Effect of adsorbed poly(ethylene glycol) on the gelation evolution of Laponite suspensions: Aging time-polymer concentration superposition

► Gelation kinetics of Laponite/PEG suspensions were monitored by small amplitude oscillatory shear (SAOS) rheology. ► Time-PEG concentration-NaCl concentration superposition was observed. ► The effect of PEG on the gelation kinetics was quantitatively modeled by a model of interaction-limited coagulation.
