Abstract

Abstract Polyurethanes (PUs) have been versatilely applied in various fields because of their preferable properties with both elasticity and hardness. Due to the thermodynamic incompatibility of hard segments and soft segments, the PUs generally have the microphase-separated structures, which could dramatically affect their chemical and mechanical properties. In this review, the characterization methods of microphase-separated structures in PU polymers, such as fourier transformed infrared spectroscopy (FTIR), atomic force microscopy (AFM), differential scanning calorimetry (DSC), and small-angle X-ray scattering (SAXS) are summarized and illustrated. The relationship between microphase-separated structures and PU properties is also discussed. This review will lay the theoretical foundation for the improvement on the application performance of PUs.

表征方法在聚氨酯材料中的应用:微相分离结构分析

摘要聚氨酯(pu)由于具有良好的弹性和硬度，在各个领域得到了广泛的应用。由于硬段和软段的热力学不相容性，pu普遍存在微相分离结构，这将极大地影响其化学和力学性能。本文综述了聚氨酯聚合物微相分离结构的表征方法，如傅里叶变换红外光谱(FTIR)、原子力显微镜(AFM)、差示扫描量热法(DSC)和小角度x射线散射(SAXS)等。讨论了微相分离结构与聚氨酯性能的关系。本文的研究将为进一步提高pu的应用性能奠定理论基础。
