This paper reports the development of the first vitrimer based on polybenzoxazines containing disulfide bonds and cardanol. The synthesis of the monomer was carried out following a sustainable process, without any solvent and purification. The novel polybenzoxazine can be recycled, reshaped and (re)processed, thanks to a fast relaxation process (18 seconds at 120 °C) and low activation energy (64.5 kJ mol⁻¹). Furthermore, the benzoxazine vitrimer shows significant and healable adhesive properties over short times and at low temperatures. These features support it also being considered in additive manufacturing applications, with the possibility of applying 3D printing technology, extending its application to many fields of materials.

一种基于腰果酚的聚苯并恶嗪三聚体：回收，重塑和可逆粘附

本文报道了第一个基于聚苯并恶嗪的含二硫键和腰果酚的玻璃微粉的开发。单体的合成按照可持续的方法进行，无需任何溶剂和纯化。由于快速的松弛过程（120°C下为18秒）和低活化能（64.5 kJ mol ^-1），新型聚苯并恶嗪可以回收，重塑和（再）加工。此外，苯并恶嗪三聚体在短时间内和低温下显示出显着且可修复的粘合性能。这些功能也支持在增材制造应用中加以考虑，并有可能应用3D打印技术，从而将其应用扩展到许多材料领域。
