Graphitic carbon nitride (g-C3N4) 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-C3N4) 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-C3N4) 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-C3N4 filler. The leading purpose of this review is to stress the significance of g-C3N4 as a reinforcement material in polymer composites.
