Zwitterionic Polyurethane(两性离子聚氨酯)研究综述
Zwitterionic Polyurethane 两性离子聚氨酯 - Here, a family of zwitterionic polyurethanes (ZPU) with sulfobetaine groups in the polymer backbone is developed, which are fabricated into encapsulation devices with tunable nanoporous structures via electrospinning. [1] In this research, we designed a novel series of zwitterionic polyurethane (zPU) additives to impart anti-thrombotic properties to a polyvinyl chloride (PVC) matrix. [2] Our device benefits from the zwitterionic polyurethane-modified cellulose acetate (PCBU-CA) membrane, which can greatly inhibit the surface fouling of blood cells and membrane flux decline. [3]在这里，开发了一系列在聚合物主链中具有磺基甜菜碱基团的两性离子聚氨酯 (ZPU)，通过静电纺丝将其制成具有可调纳米孔结构的封装装置。 [1] 在这项研究中，我们设计了一系列新型两性离子聚氨酯 (zPU) 添加剂，为聚氯乙烯 (PVC) 基质赋予抗血栓形成特性。 [2] 我们的设备受益于两性离子聚氨酯改性醋酸纤维素（PCBU-CA）膜，可以极大地抑制血细胞表面污染和膜通量下降。 [3]
Novel Zwitterionic Polyurethane
To eliminate the undesired bacterial attachment on PU coatings, we designed a novel zwitterionic polyurethane (ZPU) with high content of sulfobetaine zwitterionic moieties for enabling surface hydrophilicity to hydrophobic acrylic polyurethane (APU) via an inter-diffused structured coating. [1] In this paper, novel zwitterionic polyurethane containing pendant carboxyl-pyridinium were successfully prepared with N,N-bis(2-hydroxyethyl) isonicotinamide (BINA) and hexamethylene diisocyanate (HDI), followed by zwitterionization with 4-bromobutyric acid. [2]为了消除 PU 涂层上不希望的细菌附着，我们设计了一种新型两性离子聚氨酯 (ZPU)，它具有高含量的磺基甜菜碱两性离子部分，可通过相互扩散的结构化涂层实现疏水性丙烯酸聚氨酯 (APU) 的表面亲水性。 [1] 本文以N,N-双（2-羟乙基）异烟酰胺（BINA）和六亚甲基二异氰酸酯（HDI）为原料，采用4-溴丁酸进行两性离子化，成功制备了新型含羧基吡啶的两性离子聚氨酯。 [2]
