Abstract

See full text

Polyhexahydrotriazine (PHT) and polyhemiaminal (PHA) materials form highly cross-linked polymers which can be used as binder resins in composite materials. A filler element functionalized with a primary amine group can be covalently bonded to the PHA/PHT polymer resins. Example filler elements include, without limitation, carbon nanotubes, silica materials, carbon and glass fibers, and nanoparticles. Filler materials are incorporated into polymeric materials to improve the mechanical strength or other characteristics of the polymeric material for various applications. Typical composite materials use thermosetting materials that, once set, are intractable. PHT and PHA materials can be reverted to starting materials by exposure to acids. Thus, composite components formed using these materials are recyclable.
