Abstract: | A new type of elastomeric composite containing natural rubber (NR) and graphitic carbon nitride (g-C3N4) has been successfully prepared with the reinforced property. The reinforcing effect of g-C3N4 in NR composites was examined by cure, mechanical, morphological, and swelling studies. Besides, epoxidized NR with 50-mol % epoxy level (ENR-50) was used as a compatibilizer to enhance the hydrophilic g-C3N4 filler capacity for hydrophobic NR composites. At the same filler load level, the mechanical properties of NR/g-C3N4 composites, such as tensile strength and tensile modulus, were consistently increased with increased ENR-50 content. To note, the ENR compatibilized composites have shown better-reinforced performance, which has been attributed to the hydrogen bonding interactions between the uncondensed amine groups in g-C3N4 and the polar groups in ENR. We believe that these newly prepared NR composites based on g-C3N4 as nonblack filler and ENR-50 as compatibilizer can find potential applications in modern day rubber research. © 2019 Wiley Periodicals, Inc.
