摘要

将具有聚集诱导发光(AIE)特性的多功能基团四-(4-羟基苯)乙烯(TPE-TOH)引入聚氨酯网络结构中。TPE-TOH作为超分子交联点，显著增强了聚氨酯链段间的氢键作用力，从而提升了网络结构的完整性，同时赋予材料优异的光学功能。实验结果表明，所得聚氨酯材料HTPU-3表现出优异的综合力学性能，包括高达(54.2±7.6) MPa的拉伸强度、(311.4±17.6) MJ·m

−3

的韧性以及(1264.3±25.2)%的断裂伸长率；同时，该材料具备高透明度(透光率达85%)及可调控的荧光发射行为。基于此，构建了简单有效的二进制图案防伪系统，实现信息的加密与识别。该工作为高性能多功能聚氨酯材料的设计与应用提供了新思路。

Abstract

This study innovatively introduces the multifunctional group tetrakis-(4-hydroxyphenyl)ethylene (TPE-TOH) with aggregation-induced emission (AIE) properties into the polyurethane network structure. TPE-TOH acts as a supramolecular crosslinking point

significantly enhancing the hydrogen bonding forces between polyurethane segments

thereby improving the integrity of the network structure while conferring excellent optical properties to the material. Experimental results show that the resulting polyurethane material HTPU-3 exhibits outstanding comprehensive mechanical properties

including a tensile strength of up to (54.2±7.6) MPa

toughness of (311.4±17.6) MJ·m

−3

and an elongation at break of (1264.3±25.2)%; additionally

the material possesses high transparency (light transmittance of 85%) and tunable fluorescent emission behavior. Based on this

a simple and effective binary pattern anti-counterfeiting system was developed to achieve information encryption and identification. This work provides new insights into the design and application of high-performance multifunctional polyurethane materials.
