Modified Rheokinetic Technique to Enhance the Understanding of Microcapsule-Based Self-Healing Polymers
A modified rheokinetic technique was developed to monitor
the polymerization
of healing monomers in a microcapsule-based, self-healing mimicking
environment. Using this modified technique, monomers active toward
ring-opening metathesis polymerization (ROMP) were either identified
or disregarded as candidates for incorporation in self-healing polymers.
The effect of initiator loading on the quality and speed of healing
was also studied. It was observed that self-healing polymers have
upper and lower temperature limits between which the healing mechanism
performs at optimal levels. Also, a study of the quality of healing
cracks of different thicknesses was performed, and it was discovered
that above a critical crack thickness value, the quality of self-healing
diminishes substantially; reasons for this phenomenon are discussed
