Characterization of solvent-filled polyurethane/urea-formaldehyde core-shell composites

Véronique Michaud, Sam Neuser, Erica Manfredi

Encapsulation of liquid phases is a crucial step in many self-healing material systems where a healing agent has to be protected during processing and then released during a damage event. In this work, the mechanical properties of polyurethane (PU) reinfor ...
