Abstract:Here, we have explored
covalent adaptable networks (CANs) comprising
poly(thiourethane)-based systems (PTUs). The PTUs were synthesized
through the combination of thiol and isocyanate monomers in stoichiometric
proportions, in the presence of dibutyltin dilaurate (DBTDL) as catalyst.
Dynamic mechanical analysis (DMA) provided detailed insight into the
vitrimeric behavior. Through these investigations, we evaluated the
viscoelastic, thermomechanical, and vitrimeric properties. Additionally,
broadband dielectric… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
