TEM images of PS700+nC60-stir. (a) Amorphous structure. (b) Higher magnification of (a). (c) Crystalline structure. (d) Higher magnification of (c). (e) Disintegration of 2-mm PS700 pellets by nC60-stir after 3 d equilibration (initial conditions: 0.15 g PS700, 0.149 mg L−1 nC60-stir, and 10 mM NaCl). The insets in (b) and (d) confirm the amorphous and crystalline nature of structures.
