Low ceiling temperature polymers like cyclic poly(phthalaldehyde) are readily triggered to depolymerize via acid and heat, however these techniques are not easily accessible for on demand depolymerization. My work focuses on new methods of triggering transience via redox stimuli in cyclic poly(phthalaldehyde) materials and strategies of generating deconstructable thermosets via energy efficient frontal polymerization.

In chapter 4, we apply photoacid generators to generate photo-triggerable microcapsule for payload release systems.

Dihydrofuran was found to have multifunctionality in FROMP, acting as both a potent inhibitor and as a cleavable moiety that enables thermoset deconstruction.
