Abstract

Polymeric materials play a central role in cutting edge technologies such as biomedical devices, organic semiconductors and catalysis. Their growing demands, however, necessitate diversity in our fabrication library. Specifically, soft approaches are desired when considering incentives for scale up and the inherent vulnerability of polymers. Here, we explore unconventional approaches across different classes of polymeric materials. 1) Application of solvated free electrons for end group-free, room temperature rapid polymerization. These subatomic initiators trigger a bi-mechanistic reaction that opens the pathway to complex block-polymer architectures. 2) Metal particles as precursors to coordination polymers where nanomaterials can be realized at ambient temperature and pressure in a quantitative reaction. 3) Mechanically responsive composites fabricated with kinetically trapped metastable undercooled particles. 4) Multiscale hierarchical nanocomposites using supramolecular assemblies whereby facile control over periodicity is established by secondary interacting small molecules.
