Recent environmental issues have driven the development of bioderived chemicals for new composite materials and recycling methods. This paper presents the use of tannic acid (TA)-based epoxy as a polymeric matrix for fabricating and recycling carbon-fiber-reinforced plastic (CFRP). TA plays a critical role in increasing the adhesion of the interface between a polymeric matrix and carbon fiber (CF), ultimately improving the mechanical properties of the CFRP. In addition, its char forming ability endows the CFRP with flame-retarding and smoke-suppressing properties. TA-based CFRP can be treated with supercritical deionized water (scDW) with no additives, producing carbon spheres from the degradation of the epoxy matrix and clean CFs. Each product can be applied as various materials for different purposes. In this paper, a new paradigm is suggested to fully recycle epoxy-based CFRP composites.

最近的环境问题驱动了用于新的复合材料和再循环方法的生物衍生化学品的开发。本文介绍了基于鞣酸（TA）的环氧树脂作为聚合物基体在制造和回收碳纤维增强塑料（CFRP）中的用途。TA在增加聚合物基体和碳纤维（CF）之间界面的粘合力，最终改善CFRP的机械性能方面起着至关重要的作用。此外，它的焦炭形成能力使CFRP具有阻燃和抑烟性。基于TA的CFRP可以用不含添加剂的超临界去离子水（scDW）处理，通过环氧基质和清洁CFs的降解产生碳球。每种产品都可以用作各种材料用于不同目的。在本文中，
