Abstract
A UV-curable and recyclable thermoset shape memory polymer is provided. The polymer includes a vitrimer-based monomer and a photoinitiator. The vitrimer-based monomer includes a first unit rendering a high chain stiffness upon polymerization of the monomer, and a second photopolymerizable unit for photopolymerization of the monomer under a UV irradiation. The polymer has high strength, high stiffness, high recovery stress, high energy storage, reasonable recycling efficiency, and is printable using SLA with high resolution.
