Henghua Jin, Chris L. Mangun, Anthony S. Griffin, Jeffrey S. Moore, Nancy R. Sottos and Scott R. White Microcapsules: Thermally Stable Autonomic Healing in Epoxy using a Dual-Microcapsule System (Adv. Mater. 2/2014) Advanced Materials 26
Hollow poly(urea-formaldehyde) microcapsules are vacuum infiltrated with a reactive amine curing agent. They are used in dual capsule epoxy-amine healing chemistry to produce thermally stable self-healing epoxy polymers by Scott R. White and co-workers on page 282. Autonomic healing in excess of 90% is achieved in a high Tg (152–213 °C) structural polymer cured at high temperature (121–177 °C).
