Abstract

Thermoplastic polyurethane (TPU) has been widely utilized in varied fields due to their excellent properties such as flexibility, stretchability, thermal stability, resilience, etc. However, it is relatively difficult to control their properties comparing to PU because most of TPU properties are decided in synthetic level. Herein, aromatic polyols were introduced into desired TPU in synthetic level to overcome the issue and improve mechanical properties of TPU. Furthermore, the optimization condition is suggested by controlling the molar ratio of aliphatic/aromatic polyols. Finally, porous TPU sheets were fabricated via VIPS method using synthesized TPU. Tensile and compression testing were executed to compare the mechanical properties of each TPU and porous TPU sheet according to the molar ratio of aliphatic/aromatic polyols.

通过采用不同类型的低聚物控制热塑性聚氨酯泡沫的性能

热塑性聚氨酯（TPU）具有柔韧性、伸展性、热稳定性和回弹性等优良特性，已被广泛应用于各个领域。然而，与聚氨酯相比，由于热塑性聚氨酯的大部分特性是由合成水平决定的，因此很难控制其特性。为此，在合成阶段将芳香族多元醇引入所需热塑性聚氨酯中，以克服这一问题并改善热塑性聚氨酯的机械性能。此外，还通过控制脂肪族/芳香族多元醇的摩尔比提出了优化条件。最后，使用合成的热塑性聚氨酯通过 VIPS 方法制造出多孔热塑性聚氨酯片材。根据脂肪族/芳香族多元醇的摩尔比，通过拉伸和压缩测试比较了每种热塑性聚氨酯和多孔热塑性聚氨酯片材的机械性能。
