Graphitic carbon nitride (g‐C 3 N 4 ) reinforced polymer nanocomposite systems—A review

Research on polymer matrix‐enhancement using a carbon nanomaterial as the high‐potential filler has attracted considerable attention to meet the increasing demand for advanced polymer composites which show promising applications in a wide variety of fields. Graphitic carbon nitride (g‐C 3 N 4 ) is the most stable allotrope of carbon nitrides and its inherent electron‐rich properties, basic surface functionalities, and hydrogen bond motifs make it a potential candidate in catalysis and in other fields. This article reviews a new application of graphitic carbon nitride (g‐C 3 N 4 ) as a reinforcement material into polymer composites. It focuses on the enhancement of tribological, thermomechanical, self‐healing, anticorrosion, and flame‐retardant properties hybrid composite materials via the incorporation of g‐C 3 N 4 filler. The leading purpose of this review is to stress the significance of g‐C 3 N 4 as a reinforcement material in polymer composites.
