Functionalized Polyurethane(功能化聚氨酯)研究综述
Functionalized Polyurethane 功能化聚氨酯 - Bacterial infection and blockage are severe problems for polyurethane (PU) catheters and there is an urgent demand for surface-functionalized polyurethane. [1] The present study gives an investigation on the physico-chemical property changes occurred for the β-cyclodextrin (CD) functionalized polyurethane (PU) fibrous membranes. [2] An acryl-functionalized polyurethane (PU) series was successfully synthesized using poly(tetramethylene ether) glycol-methylene diphenyl diisocyanate (PTMG-MDI) oligomer based on urethane methacrylates to control the flexibility of photo-cured 3D printing architectures. [3] The better flexibility of the soft phase in the PEG-functionalized polyurethanes compared to the pristine polyurethane (PU) was presumably also responsible for the higher ability of the polymer to uptake water. [4] In this work, anthracene-tailored trifunctionalized polyurethane (PU) prepolymers were synthesized, and these prepolymers formed crosslinked structures via the dimerization of anthracene groups under UV irradiation. [5]细菌感染和堵塞是聚氨酯（PU）导管的严重问题，迫切需要表面功能化的聚氨酯。 [1] 本研究对β-环糊精（CD）功能化聚氨酯（PU）纤维膜发生的物理化学性质变化进行了研究。 [2] 使用基于聚氨酯甲基丙烯酸酯的聚（四亚甲基醚）二醇-亚甲基二苯二异氰酸酯（PTMG-MDI）低聚物成功合成了丙烯酸官能化聚氨酯（PU）系列，以控制光固化 3D 打印结构的柔韧性。 [3] 与原始聚氨酯 (PU) 相比，PEG 官能化聚氨酯中软相更好的柔韧性可能也是聚合物吸收水能力更高的原因。 [4] 在这项工作中，合成了蒽定制的三官能化聚氨酯（PU）预聚物，这些预聚物在紫外线照射下通过蒽基团的二聚形成交联结构。 [5]
