由于人类对可持续发展的渴望，利用可再生资源合成具有独特性能的生物基热固性树脂引起了越来越多的关注。然而，由于自然界中缺乏天然来源的二胺，二胺衍生的生物双苯并恶嗪树脂很少被报道。在这里，我们使用各种单酚（愈创木酚/芝麻酚/紫檀芪）和二胺（Priamine 1074）作为天然可再生原料，通过绿色合成方法报告了一系列生物基双苯并恶嗪树脂。这些双苯并恶嗪的化学结构细节通过核磁共振、傅里叶变换红外光谱和尺寸排阻色谱进行了表征。通过差示扫描量热热谱图和原位 FT-IR 分析研究了热活化聚合行为。此外，通过接触角测量研究了每种树脂的表面性质，在不同的聚合循环前后，这一系列 Priamine 1074 衍生的生物树脂涂层的表面自由能值没有太大变化。此外，通过动态力学分析和热重分析评估了完全聚合的生物树脂的热稳定性。这些生物聚苯并恶嗪均表现出良好的热性能这一系列 Priamine 1074 衍生的生物树脂涂层在不同的聚合循环之前和之后都获得了没有太大变化的表面自由能值和表面自由能值。此外，通过动态力学分析和热重分析评估了完全聚合的生物树脂的热稳定性。这些生物聚苯并恶嗪均表现出良好的热性能这一系列 Priamine 1074 衍生的生物树脂涂层在不同的聚合循环之前和之后都获得了没有太大变化的表面自由能值和表面自由能值。此外，通过动态力学分析和热重分析评估了完全聚合的生物树脂的热稳定性。这些生物聚苯并恶嗪均表现出良好的热性能T _d10大于 350 °C。因此，这一新系列的生物基双苯并恶嗪热固性树脂及其相应的聚苯并恶嗪表现出出色的表面和热性能，为高性能聚合物涂层材料提供了巨大的潜在应用。

Biobased Bisbenzoxazine Resins Derived from Natural Renewable Monophenols and Diamine: Synthesis and Property Investigations

Synthesizing biobased thermosetting resins with unique performance from renewable resources has attracted increasing attention because of the sustainable development aspirations from human beings. However, diamine-derived bio-bisbenzoxazine resins have rarely been reported because of the lack of naturally sourced diamines in nature. Here, we report a series of biobased bisbenzoxazine resins via green synthetic methods using various monophenols (guaiacol/sesamol/peterostilbene) and a diamine (Priamine 1074) as natural renewable raw materials. Chemical structural details of these bisbenzoxazines were characterized by nuclear magnetic resonance, Fourier transform infrared spectroscopy, and size exclusion chromatography. Thermally activated polymerization behaviors were investigated by differential scanning calorimetry thermograms and in situ FT-IR analysis. Besides, surface properties of each resin were studied through the contact angle measurement, and surface-free-energy values without varying too much were achieved from this series of Priamine 1074-derived bioresin coatings before and after different polymerization cycles. Moreover, thermal stability of the fully polymerized bioresins was evaluated by dynamic mechanical analysis and thermogravimetry analyses. These bio-polybenzoxazines all showed good thermal properties with T_d10 greater than 350 °C. Consequently, this new family of biobased bisbenzoxazine thermosetting resins and their corresponding polybenzoxazines exhibit outstanding surface and thermal performances, providing great potential applications for high-performance polymeric coating materials.
