Abstract

There has been recent discoveries in the field of self-healing polymers. Self-healing polymers are polymers that have the ability to regenerate after being damaged or withstand larger amounts of damage. The purpose of this experiment was to test the the healing rate of a self healing polymer based on dynamic hindered urea bonds when the self-healing polymer suffered multiple perforated sites in close proximity to each other. It was hypothesized that if the number of puncture sites were increased, then the healing rates of the self-healing polymer would decrease. The healing rate was tested by puncturing the self healing polymer, then recording the circumference of the perforated site, allowing the self-healing polymer to heal in a set amount time. Then, the circumference of the puncture site was measured again. The healing rate was calculated as the change in circumference per that set amount of time.
