Abstract

Polyurethane (PU) is a synthetic polymer with a micro-phase separation structure and tunable mechanical properties. Since the first successful application of thermoplastic polyurethane (TPU) in vivo in 1967, PU has become an important biomedical material for various applications in tissue engineering, artificial organs, wound healing, surgical sutures, medical catheters, and bio-flexible electronics. This review summarizes three strategies for regulating the mechanical properties of medical PU elastomers, including monomer design and selection, modification and arrangement of segments, and incorporation of nanofillers. Furthermore, we discuss the feasible strategies to achieve the biodegradability and self-healing properties of polyurethane to meet specific biomedical needs. Finally, this review highlights the latest advancements in functionalized PU for biomedical applications and offers insights into its future development.

功能性聚氨酯弹性体的最新进展:从结构设计到生物医学应用。
聚氨酯(PU)是一种具有微相分离结构和可调力学性能的合成聚合物。自1967年首次在体内成功应用热塑性聚氨酯(TPU)以来,PU已成为一种重要的生物医学材料,在组织工程、人造器官、伤口愈合、手术缝合线、医用导管和生物柔性电子等领域有各种应用。本文综述了调节医用PU弹性体力学性能的三种策略,包括单体的设计与选择、段段的修饰与排列以及纳米填料的掺入。此外,我们讨论了可行的策略来实现聚氨酯的生物降解性和自愈性,以满足特定的生物医学需求。最后,本文综述了功能化聚氨酯在生物医学应用方面的最新进展,并对其未来的发展进行了展望。
