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.

A core-shell gradient ternary precursor and a preparation method and application thereof. The preparation method includes (1) mixing a terephthalic acid solution with alkaline liquor to obtain a terephthalic acid salt solution, adding a nickel source solution for a reaction to obtain a Ni-MOF solution, mixing the Ni-MOF solution with ammonia water, and adjusting a pH value to obtain a base solution; and (2) adding a nickel-cobalt-manganese ternary mixed salt solution, a liquid alkali solution, and an ammonia-water solution simultaneously to the base solution obtained in step (1) for a co-precipitation reaction, and obtaining the core-shell gradient ternary precursor after aging treatment. The Ni-MOF is pre-prepared and used as a core for the co-precipitation reaction, to obtain the core-shell like precursor with a gradient. Carbon in the core of the core-shell gradient ternary precursor reacts with oxygen, thereby reducing a nickel oxidation state on particle surfaces and reducing crack generation.
