Abstract

Biobased reprocessable polyurethane (PU) networks have drawn significant attention due to limited petroleum resources and aggravating environmental issues. However, the preparation of biobased PU networks with simultaneous efficient flame-retardant, antioxidative, self-healing and reprocessing performance is a great challenge due to the complicated structural design required. A novel strategy to fabricate multifunctional PU networks containing dynamic phenol–carbamate bonds from biobased naringenin and vanillin has been developed. First, a vanillin-based diol containing organic phosphorus moieties (VD) was prepared. Then modified diol and naringenin were combined to produce a self-healable, recyclable, antioxidative and flame-retarded PU (NVP-x)s where x represents the molar ratio of n[-OH_(VD)] / n{[-OH_(naringenin)] + [-OH_(VD)] + [-OH_(PTMG)]} possesses excellent flame-retardant, antioxidative, self-healing and reprocessing performance due to the presence of dynamic phenol–carbamate bonds, organophosphorus and phenolic moieties. An effective approach to the manufacture of multifunctional PUs with a potential application in the field of self-healing and flame-retardant coating, wound dressing membranes and fire-control engineering materials has been demonstrated.

由生物基柚皮苷和香兰素制成的具有阻燃、抗氧化、自愈和再加工能力的坚固聚氨酯网络

由于石油资源有限和环境问题日益严重，生物基可再加工聚氨酯（PU）网络备受关注。然而，由于需要复杂的结构设计，制备同时具有高效阻燃、抗氧化、自愈和再加工性能的生物基聚氨酯网络是一项巨大的挑战。我们开发了一种新策略，利用生物基柚皮苷和香兰素制造含有动态苯酚-氨基甲酸酯键的多功能聚氨酯网络。首先，制备了含有有机磷分子的香兰素基二醇（VD）。x 代表 n[-OH(VD)] / n{[-OH(naringenin)] + [-OH(VD)] + [-OH(PTMG)]} 的摩尔比、由于含有动态苯酚-氨基甲酸酯键、有机磷和酚类分子，因此具有优异的阻燃、抗氧化、自愈和再加工性能。该研究展示了一种制造多功能 PU 的有效方法，其在自愈合和阻燃涂层、伤口敷料膜和防火工程材料领域具有潜在的应用前景。
