“…However, the processibilities of the above modified systems are deteriorated, such as the high viscosity and curing temperature. On the other hand, some thermosetting resins such as epoxy [13], PR [14] and polyimide resins have been blended with BZs to lower the curing reaction temperature or improve the toughness of BZs. Nevertheless, the improvement of the properties is limited because of the weak connection or no connection between BZ and thermosetting resin.…”

“…The first stage was mainly the curing reaction of LCE and imidazole. As the curing reaction proceeded, reaction‐induced phase separation occurred to form liquid crystalline phase, which was further fixed in a cross‐linking network of PEI . The second stage was the ring‐opening polymerization of Bz monomer, which generated another cross‐linking network of PBz.…”

A diamine‐based benzoxazine monomer (Bz) and a liquid crystalline epoxy monomer (LCE) are synthesized, respectively. Subsequently, a benzoxazine‐epoxy interpenetrating polymer network (PBEI) containing liquid crystalline structures is obtained by sequential curing of the LCE and the Bz in the presence of imidazole. The results show that the preferential curing of LCE plays a key role in the formation mechanism of liquid crystalline phase. Due to the introduction of liquid crystalline structures, the thermal conductivity of PBEI increases with increasing content of LCE. When the content of LCE is 80 wt %, the thermal conductivity reaches 0.32 W m−1 K−1. Additionally, the heat‐resistance of PBEI is superior to liquid crystalline epoxy resin. Among them, PBEI55 containing equal weight of Bz and LCE has better comprehensive performance. Its thermal conductivity, glass transition temperature, and the 5 % weight loss temperature are 0.28 W m−1 K−1, 160 °C, and 339 °C, respectively. By introducing boron nitride (BN) fillers into PBEI55, a composite of PBEI/BN with the highest thermal conductivity of 3.00 W m−1 K−1 is obtained. © 2017 Wiley Periodicals, Inc. J. Polym.

“…High polymerization temperature (160–260 °C) is inconvenient for many applications . More than that, pure monomer–based BZ resins exhibit relatively high brittleness that limits their processing, especially into thin films and coatings …”

The synthesis of composite materials based on various carbon structures and polybenzoxazines (PBZs) gives products with noticeable thermal, electrical, and mechanical properties. The role of different carbon materials is emphasized in terms of the main advantages in both structure and properties. On the other hand, the PBZ features are significant considering the high glass transition temperatures, low flammability, high char yields, and good thermal stability. This review article describes the synthesis, structure, and properties of polybenzoxazine composites based on carbon fibers, carbon nanotubes, graphene, graphene oxide, and other carbonaceous materials. Particular attention is given to the interactions possible to occur between the polybenzoxazine matrix and carbon component.
