Imagine a polymer with removable parts that can deliver something to the environment and then be chemically regenerated to function again. Or a polymer that can contract and expand the way muscles do. These functions require polymers with both rigid and soft nano-sized compartments with extremely different properties. Researchers have developed a hybrid polymer of this type that might one day be used in artificial muscles; for delivery of drugs or biomolecules; in self-repairing materials; and for replaceable energy sources.
