摘要

本文综述了分段热塑性聚氨酯和聚氨酯(TPU)的结构-形态-性能关系。特别强调了软段结构、极性和分子量、二异氰酸酯的对称性以及氢键的性质、程度和强度对tpu的形貌和热力学性能的影响。通过不同的技术得到的与组分相关的TPU形貌和性能的实验结果也与量子力学计算和分子动力学模拟等计算方法生成的形貌曲线进行了比较

Influence of soft segment structure, hydrogen bonding, and diisocyanate symmetry on morphology and properties of segmented thermoplastic polyurethanes and polyureas

A comprehensive review of the structure-morphology-property relations in segmented thermoplastic polyurethanes and polyureas (TPU) is provided. Special emphasis is given to the influence of the soft segment structure, polarity, and molecular weight, diisocyanate symmetry and the nature, extent, and strength of hydrogen bonding on the morphology and thermal and mechanical properties of TPUs. Experimental results obtained on composition-dependent TPU morphology and properties by various techniques were also compared by the morphology profiles generated by computational methods such as quantum mechanical calculations and molecular dynamics simulations
