TEM images acquired at three different tilt angles (labeled) from SM/FS-MA nanocomposites containing 5 and 20 wt% FS-MA (top and bottom rows, respectively). In each case, the FS-MA nanoparticles appear as electron-opaque (dark) aggregate features, whereas the styrenic lamellae of the SM copolymer are likewise dark due to selective staining. The arrow shows the location of lamellae comprising the copolymer nanostructure, whereas the circled region highlights copolymer lamellae that appear distorted or partially discontinuous
