Supramolecular chemistry has garnered significant attention in materials science. This is because noncovalent interactions enable the addition of unique behavior to otherwise covalent systems. The ...

Thermosetting polyurethanes have excellent elastic properties and solvent resistance, but they cannot be reshaped like thermoplastic polymers after molding. In this study, we designed a thermosetting ...

Even laser-launched micro bullets could not penetrate the new material developed by the Army Research Laboratory (ARL) during tests this month. Made out of polyurethane urea elastomers (PUUs), rather ...
