Characterisation of polymer-based self-healing materials

Sam McDonald
Project Completed

Scientific Case

With regards to polymer-based self-healing materials, the healing process is based on the presence of microcapsules intentionally embedded into the matrix material. The content of these capsules (such as a monomer) activates upon mechanical damage; the monomer polymerises in the crack plane with the help of a catalyst, which results in a rebinding of the crack faces. We will use phase contrast X-ray microtomography to observe the capsules in 3-D before and after activation, with the aim of aiding in the tailoring of capsule activation.
