a Temporal evolution of dewetting velocity \(\left(V({t}_{{{{\rm{dew}}}}})=\frac{dR}{d({t}_{{{{\rm{dew}}}}})}\right)\) for pure PS and PNC thin films of thickness 207 ± 1 nm dewetted at Tdew = 200 °C for tdew = 200 s. b Complex viscosity (∣η*∣) calculated from melt rheology experiments (Trheo = 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 Tdew = 200 °C is shown as a function of tdew. 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).
