Abstract
Elastomers synthesized by vat photopolymerization suffer from poor mechanical properties due to low molecular weight and limited chain entanglement, while increasing entanglement improves toughness at the cost of resin viscosity and printability. This study proposes a strategy combining molecular architecture design and nanosheet integration, successfully achieving high-precision (100 μm) 3D printing of ultraviolet UV-curable polyurethane-urea acrylate (PUUA) elastomers with excellent comprehensive properties. Specifically, a chain extender containing urea bonds was first introduced into polyurethane prepolymer, and then mixed with a photoinitiator, reactive diluent and zirconium phosphate (ZrP) nanosheets, to…
