Mushroom Nanostructures Stupp et al. (34) have evolved strategies to create supramolecular units of various sizes and shapes via self-assembly. They found that rod-coil block copolymers can self-assemble into long striplike aggregates measuring 1 m or more in length and a few nanometers in other dimensions. The mushroom nanostructures in Figure 14.8 constitute yet another...
