ABSTRACT

Polyurethanes are highly sought after polymer materials due to their exceptional properties. These properties can be expanded by including 2-hydroxyethyl salicylate in its chemical structure in order to obtain active polymer materials with anti-inflammatory and analgesic properties. These polymers can be used in the manufacture of footwear, stockings and clothing. Furthermore, in order to improve mechanical properties, glycerol and its derivatives with various hydroxy-aliphatic chains can be incorporated into the polyurethanes. Changing the chemical structure of the hard segment (through chain extender amount and crosslinker’s structure) may yield improved or modified properties and uses for these polyurethanes, which can be identified by investigating the structure–property relationships for these materials. The incorporation of a crosslinker with longer hydroxy-aliphatic chains (glycerol ethoxylate (Star-PEG)) has significantly improved the mechanical resistance of the polyurethane. At the same time, Star-PEG-polyurethane preserved its very good properties after a year of outdoor environmental exposure, without exposure to direct sunlight. The inclusion of the salicylate component in the polyurethane hard segments develops new and interesting ways to obtain polyurethane elastomers for biomedical applications. We intend to study in detail the medical properties of these polyurethane materials and their maintenance over time in a future paper.

摘要

聚氨酯因其卓越的性能而备受追捧。这些特性可以通过在其化学结构中包含水杨酸2-羟乙酯来扩展，以获得具有抗炎和镇痛特性的活性聚合物材料。这些聚合物可用于制造鞋类、长袜和服装。此外，为了改善机械性能，可以将具有各种羟基脂肪链的甘油及其衍生物掺入聚氨酯中。改变硬链段的化学结构（通过扩链剂的量和交联剂的结构）可能会改善或改进这些聚氨酯的性能和用途，这可以通过研究这些材料的结构-性能关系来确定。掺入具有较长羟基脂肪链的交联剂（甘油乙氧基化物 (Star-PEG)）显着提高了聚氨酯的机械强度。同时，Star-PEG-聚氨酯在经过一年的室外环境暴露后仍保持其非常好的性能，没有暴露在阳光直射下。在聚氨酯硬链段中加入水杨酸盐成分，为获得用于生物医学应用的聚氨酯弹性体开辟了有趣的新途径。我们打算在未来的一篇论文中详细研究这些聚氨酯材料的医疗特性及其随时间的维护。Star-PEG-聚氨酯在经过一年的户外环境暴露后仍保持其非常好的特性，没有暴露在阳光直射下。在聚氨酯硬链段中加入水杨酸盐成分，为获得用于生物医学应用的聚氨酯弹性体开辟了有趣的新途径。我们打算在未来的一篇论文中详细研究这些聚氨酯材料的医疗特性及其随时间的维护。Star-PEG-聚氨酯在经过一年的户外环境暴露后仍保持其非常好的特性，没有暴露在阳光直射下。在聚氨酯硬链段中加入水杨酸盐成分，为获得用于生物医学应用的聚氨酯弹性体开辟了有趣的新途径。我们打算在未来的一篇论文中详细研究这些聚氨酯材料的医疗特性及其随时间的维护。
