Fig. 2. Dewetting dynamics and rheology of PNCs.

a Temporal evolution of dewetting velocity $\left(V\left(t_{\mathrm{dew}}\right)=\frac{dR}{d\left(t_{\mathrm{dew}}\right)}\right)$ for pure PS and PNC thin films of thickness 207 ± 1 nm dewetted at T_dew = 200 °C for t_dew = 200 s. b Complex viscosity (∣η^*∣) calculated from melt rheology experiments (T_rheo = 200 °C) using oscillatory shear as a function of shear rate. The dotted red line signifies the viscosity at a strain rate = 0.00159 s⁻¹. c Calculated viscosity using equation (2) for the pure PS and PNC thin films dewetted at T_dew = 200 °C is shown as a function of t_dew. The horizontal lines in (c) represent time-average viscosity. The error bars in the figure represent the standard deviation of the data. The legends in (b) are also applicable to (a) and (c).
