a Monomer density profiles from the surface of a NP for SN, NR4 and TP4 filled PNCs. b Monomer-monomer pair-correlation function for SN, NR4, and TP4 filled PNCs. c Monomer density profiles from the center of a TP for varying arm lengths. d Viscosity ratio (\(\frac{\eta }{{\eta }_{0}}\)) calculated from melt rheology experiments (open triangles), dewetting experiments (closed diamonds) and MD simulations (closed hexagons) as a function of normalized inaccessible volume (V *). All green symbols denotes TP5, all pink symbols denotes TP11 and all blue symbols denotes TP14. All black hexagons are results extracted from MD simulations. The black dotted line denotes viscosity ratio \(\frac{\eta }{{\eta }_{0}}\) = 1. The black solid line indicates a scaling of \(\frac{\eta }{{\eta }_{0}} \sim {({V}^{*})}^{-0.2}\). The error bars in the figure represent the standard deviation of the data.
