Figure 2

TEM images of BaSO4/PLLA nanocomposites with different filler loading at: (a) 5%, (b) 15% and (c) 20%. With increased filler loading, larger clusters of agglomerated BaSO4 nanofillers are observed. Scale bar = 200 nm for all images. (d) Size distribution of the agglomerated BaSO4 nanofillers based on n = 120 clusters/particles. The average particle size was 270 ± 105 µm in the 20% BaSO4/PLLA system.
