摘要

随着聚氨酯弹性体的广泛应用，有必要开发可回收、阻燃且具有良好机械性能的聚氨酯弹性体，以满足工业要求。在此，我们以动态硼酸酯为基础，制备了一种阻燃、可回收、强韧的聚氨酯弹性体（PIDB-1）。磷菲和含硼基团的引入赋予了 PIDB-1 极高的阻燃性，它达到了垂直燃烧（UL-94）V-0 等级。PIDB-1 薄膜具有很高的可见光透射率，在波长为 800 至 900 纳米时，其透射率达到 90%。PIDB-1 的拉伸强度为 54.9 MPa，韧性达到 207.8 kJ/m3，显示出其优越的机械性能。同时，动态硼酸酯使 PIDB-1 弹性体具有物理和化学可回收性。当使用 PIDB-1 作为碳纤维增强聚合物复合材料的聚合物基体时，碳纤维可以完全回收利用。这项研究为基于动态硼酸酯键制造透明、阻燃、可回收的高强度和高韧性聚氨酯弹性体提供了一种综合设计策略，有望在不同行业得到广泛应用。

Tough, high-strength, flame-retardant and recyclable polyurethane elastomers based on dynamic borate acid esters

With the wide application of polyurethane elastomers, it is necessary to develop recyclable, fire-retardant polyurethane elastomers with great mechanical properties to comply with industrial requirements. Herein, we fabricated a flame-retardant, recyclable, strong yet tough polyurethane elastomer (PIDB-1) based on dynamic borate acid esters. The introduction of phosphaphenanthrene and boron-containing groups endow PIDB-1 with great flame retardancy, as reflected by it achieving the vertical burning (UL-94) V-0 rating. The PIDB-1 film shows high visible light transmittance, and its transmittance reaches 90 % at the wavelength of 800 to 900 nm. The tensile strength of PIDB-1 is 54.9 MPa, and its toughness reaches 207.8 kJ/m³, indicative of superior mechanical properties. Meanwhile, the dynamic borate acid esters allow the PIDB-1 elastomer to possess physical and chemical recyclability. When using PIDB-1 as a polymer matrix for carbon fiber-reinforced polymer composites, the carbon fibers can be fully recycled. This work provides an integrated design strategy for creating transparent, flame-retardant, recyclable polyurethane elastomers combining high strength and toughness based on dynamic borate ester bonds, which is expected to find wide applications in different industries.

期刊介绍： Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers. Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
