New ways to engineer composites: polymer design combines strength and reversibility

Silica nanoparticles blended into polystyrene chains (purple) distribution and hexagonal lattice. Depending on how the chain is organized on the surface of the particles, it is intertwined when compressed (purple) or untangled (blue).
