Abstract:Dual-network filler-free silicon elastomers with excellent mechanical properties and high tensile strength (>3 MPa) were fabricated through physical and chemical crosslinking via Fe 3+ ion coordination and aza-Michael addition, respectively. Dynamic mechanical analysis and loading− unloading tests were used to analyze the sacrificial bonds and dual networks in the elastomers. Continuous-wave electron paramagnetic resonance results revealed the incomplete coordination and similar chemical environment of Fe(III)… 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.
