With the growing demand for high performance polymeric materials in industry, several types of thermosets such as bismaleimides, advanced epoxy resins, cyanate esters, and phenolic resins have been widely investigated to improve the performance of thermosetting products. Among them, benzoxazine resins have received wide attention due to their extraordinarily rich molecular design flexibility, which can customize our needs and adapt increasing requirements. To further improve the properties of polybenzoxiazines, researchers have found that the introduction of a norbornene functional group into the benzoxazine moiety can effectively improve the comprehensive performance of polybenzoxazine thermosets. This article focused on reviewing the recent development of high-performance thermosets based on norbornene functional benzoxazine thermosetting resins.
随着工业对高性能聚合物材料的需求不断增长，几种热固性材料如双马来酰亚胺、先进环氧树脂、氰酸酯和酚醛树脂已被广泛研究，以提高热固性产品的性能。其中，苯并恶嗪树脂因其极其丰富的分子设计灵活性而受到广泛关注，这种灵活性可以满足我们的需求并适应不断增加的要求。为了进一步提高聚苯并恶嗪的性能，研究人员发现，将降冰片烯官能团引入苯并恶嗪部分可以有效提高聚苯并恶嗪热固性材料的综合性能。本文重点综述了基于降冰片烯官能化苯并恶嗪热固性树脂的高性能热固性材料的最新进展。
