摘要

本工作聚焦于聚碳酸酯二醇(PCDL)、聚己内酯二醇(PCL)及其共软段对聚氨酯弹性体(TPU)结构与性能的调控作用. 针对PCL基TPU拉伸强度偏低、且经紫外老化后力学性能大幅衰减的问题，采用半预聚分步扩链工艺，制备不同比例的PCDL/PCL共软段TPU. 借助红外光谱、原子力显微镜等表征手段，结合力学、耐磨、耐油、耐水解及耐紫外老化测试，系统研究了PCDL含量对TPU微观结构与性能的影响. 结果表明，随着PCDL占比增大，软段内部分子间相互作用增强、硬段分散更均匀，有效优化了体系微观结构，实现了“增强-调韧”的协同效应，且大幅提升了环境稳定性. 该研究为户外装饰用高性能TPU的选材与结构设计提供了重要参考，也为TPU材料的性能优化提供了新的技术思路.

Abstract

This work focused on the regulation of the microstructure and properties of thermoplastic polyurethane elastomers (TPUs)

via

poly(carbonate diol)/poly(caprolactone diol) (PCDL/PCL) co-soft-segments. Aiming at the drawbacks of PCL-based TPUs

including low tensile strength and dramatic deterioration of mechanical performances under UV aging

a semi-prepolymer two-step chain extension method was employed to fabricate a series of TPUs with varying PCDL/PCL ratios in co-soft-segments. A combination of multiple characterizations including Fourier transform infrared (FTIR) spectroscopy and atomic force microscopy (AFM)

together with mechanical

abrasion-resistant

oil-resistant

hydrolysis-resistant and UV aging resistance tests

were utilized to systematically explore the effect of PCDL content on the microstructural evolution and comprehensive performances of TPUs. The experimental results revealed that rais

ing the PCDL fraction strengthens intermolecular interactions among soft segments and promoted homogeneous dispersion of hard domains. Such structural evolution optimized the microscopic morphology of TPU matrix

endowed the material with a synergistic strengthening-toughening effect

and greatly enhanced its environmental durability. This work offers valuable guidance for material screening and molecular structure design of high-performance TPUs applied in outdoor decorative fields

and also proposes a novel technical strategy to boost the overall performances of TPU materials.
