Fig. 3: 3D morphology of fully crystallized polymers with NR-labeled silica nanoparticles.

Fig. 3

a PLA containing 1.3 wt % of 200 nm NR-labeled nanoparticles fully crystallized at 120 °C. a1 False-color solid (color scale as in Fig. 1); (a2) “porous” rendering of the same region; (a3, a4) vertical yz and xz sections along the green dotted lines in a1. Note some preference of spherulites to form vertical columns. b iPP containing 1.3 wt % of NR-labeled 200 nm SiO2 NPs fully crystallized at 135 °C. Both in PLA and in iPP the NPs tend to concentrate at spherulite boundaries.
