Figure 5

(a) The shell thickness (normalized by its value hf,0 when =0) can be tuned by delaying the pouring time by from the moment of preparation of the polymer solution. Results for both VPS-32 and PDMS are shown. (b) Viscosity of PDMS versus the sum of the measuring time, t, and the effective waiting time, δ (δ=2.02±0.02 from fitting all the curves to the master curve obtained for =0). Inset: Viscosity as measured after holding the mixture for a time in a quiescent state prior to testing in the rheometer.
