Here, we introduce a novel method for developing TPU elastomers with enhanced performance and superior functionalities compared to conventional TPUs, achieved through the use of α, ω-hydroxyl end-functionalized polyacrylates. This approach involves a defect-free synthesis of α, ω-hydroxyl end-functionalized polyacrylates through visible-light-driven photoiniferter polymerization. By strategically blending these functionalized polyacrylates with conventional polyols, we have engineered TPUs that exhibit exceptional toughness and notable self-healing capabilities, traits rarely found in existing TPUs. Furthermore, incorporating photo-crosslinkable acrylic monomers has enabled the creation of the first TPU with superior elastomeric properties and photopatterning capabilities.
