Figure 3

(a) Oscillating behaviours of the initial amplitude of the intensity correlation function, σI2 during the BZ oscillation reaction for the ABC triblock copolymer solution (5.0 wt%) at 26 °C. The correlation function was collected via 2.0 s laser irradiation. (b) Viscosity oscillation of the ABA and ABC triblock copolymer solutions at 26 °C with share rate=45 s−1. (c) Oscillating profiles of G′ and G″ of ABC triblock copolymer solution (5.0 wt%) at 30 °C, with γ=2.0% and f=1.0 Hz. (d) Direct observation of an autonomous sol-gel oscillation of the ABC triblock copolymer solution (5.0 wt%) at 30 °C. These pictures were captured from Supplementary Movie 1. The BZ substrates in the feed for the measurements were composed as follows: [HNO3]=0.81 M, [NaBrO3]=0.1 M, [MA]=0.04 M.
