“…3,29 Benzoxazine (BZ) monomers possess the ability to undergo thermal ring-opening polymerization, without the need for any catalysts and without the formation of byproducts, forming polymers with several unique features (e.g., high chemical resistance, low surface free energy, high ame retardancy) that have drawn the attention of both academia and industry. [30][31][32][33][34][35][36][37] Triphenylamine (TPA) possesses a unique two-photon absorption ability and has been studied and applied in many elds, including optoelectronic devices and electron transition devices. [38][39][40] Hence, we have been interested in combining the properties of BZ and TPA units in polymeric systems.…”

“…However, this material exhibits high brittleness, which makes it difficult to use them to prepare films or complex structures [ 81 , 82 , 83 ]. Carbon allotrope-reinforced polybenzoxazine composites were proposed to improve the mechanical properties and processibility of these composites [ 84 , 85 , 86 ]. Thus far, some studies have been conducted on the use of polybenzoxazine composites reinforced with different types of carbon allotropes as materials for BPs (see Table 5 ) [ 87 , 88 , 89 , 90 ].…”

Bipolar plates (BPs) are one of the most important components of polymer electrolyte membrane fuel cells (PEMFCs) because of their important role in gas and water management, electrical performance, and mechanical stability. Therefore, promising materials for use as BPs should meet several technical targets established by the United States Department of Energy (DOE). Thus far, in the literature, many materials have been reported for possible applications in BPs. Of these, polymer composites reinforced with carbon allotropes are one of the most prominent. Therefore, in this review article, we present the progress and critical analysis on the use of carbon material-reinforced polymer composites as BPs materials in PEMFCs. Based on this review, it is observed that numerous polymer composites reinforced with carbon allotropes have been produced in the literature, and most of the composites synthesized and characterized for their possible application in BPs meet the DOE requirements. However, these composites can still be improved before their use for BPs in PEMFCs.

“…Introducing conductive materials into insulating hosts − is an attracting topic because of the scientific and practical significance. As electrons were transported through the contact regions between adjacent nanofillers, , a short distance between nanofillers is crucial for the enhanced tunneling effect and conductivity of the nanocomposites.…”

Dispersion of large amounts of carbon fillers, such as graphene, mesocarbon microbeads, and multiwalled carbon nanotubes, in water provides a route to yield nanocomposites with superior mechanical properties and high conductivities for academic studies and practical applications. In this aspect, a self-healable polymer blend of poly(acrylic acid) (PAA) and poly(ethylene oxide) (PEO) is an excellent dispersant for carbon fillers, rendering nanocomposites with a large filler content (up to 90 wt %). As the carbon filler content increases from 10 to 90 wt %, the nanocomposites transfer from healable elastomers with a high fracture strain (up to 700%) into hard plastics with outstanding conductivities (up to 1.1 × 10 6 S m −1 ). Morphological investigations by scanning electron microscopy suggested the homogeneous dispersion of the carbon fillers in the PEO/PAA polymer blend. The experimental mechanical modulus and the conductivity of the nanocomposites as functions of the filler content can be approached by the theoretical Kolarik model and the scaling law, respectively, based on a co-continuous distribution of the carbon filler and the polymer blend. A theoretical evaluation provided in this study thereby lays the ground for future development in practical application fields.
