The molecular-level design and controlled synthesis of materials are of key importance for advancing their applications. Based on the special structure of 3-aminophenol, containing both phenol and amine groups, a facile synthesis of highly monodisperse poly(benzoxazine-co-resol)-based polymer spheres was first reported by the autocatalysis polymerization of 3-aminophenol and formaldehyde without using any catalyst, surfactants, templates, and/or functional dopants at low temperature. The sizes of polymer spheres can be widely tuned from 372 to 1030 nm by changing the initial reaction temperatures and the concentrations of monomers. Based on FTIR, NMR, XPS, and EDX analysis, 3-amoniaphenol was evidenced not only to participate in the polymerization and form the structure of polybenzoxazine but also to catalyze the polymerization. Furthermore, they can be pseudomorphically and uniformly converted to the corresponding carbon spheres in high yield due to the excellent thermal stability of 3-aminophenol–formaldehyde resin.

聚苯并恶嗪-共聚甲阶酚醛基聚合物和碳球的自催化合成

材料的分子水平设计和受控合成对于促进其应用至关重要。基于3-氨基苯酚的特殊结构,同时包含苯酚和胺基,可轻松合成高度单分散的聚(苯并恶嗪-co-氨基甲酸酯基聚合物球是通过3-氨基苯酚和甲醛的自动催化聚合反应报道的,在低温下不使用任何催化剂,表面活性剂,模板和/或功能性掺杂剂。通过改变初始反应温度和单体浓度,可以将聚合物球的尺寸从372 nm广泛地调节到1030 nm。根据FTIR,NMR,XPS和EDX分析,证明3-氨苯酚不仅参与聚合反应并形成聚苯并恶嗪的结构,而且还催化了聚合反应。此外,由于3-氨基苯酚-甲醛树脂具有出色的热稳定性,它们可以高品质地拟态和均匀地转化为相应的碳球。
