g-C3N4 nanomaterials as a novel coat for multifunctional bamboo and linen fabric.

In this work, g-C₃N₄ was successfully prepared using microwave and conventional thermal methods. The physicochemical properties of prepared graphitic carbon nitride (g-C₃N₄) were analyzed using various techniques including SEM, TEM, XRD, FTIR and UV–vis absorption spectroscopy. Thermally and microwave prepared g-C₃N₄ nanomaterials have been coated onto bamboo and linen fabrics using pad-dry-cure process. The properties of the coated fabrics were evaluated. The colony counting method was used to assess the finished fabrics' antibacterial activity against S. aureus and E. coli. Significant improvement was observed. Cellulosic fabric treated with microwave prepared (g-C₃N₄) shows higher reduction rate. UV protection properties of bamboo as well as linen fabric improved as indicated by UPF Values. Linen fabric treated by thermally prepared g-C₃N₄ indicated the highest UPF value recorded (47.5). Post treatment of g-C₃N₄ nanomaterials fabric by stearic acid enhance hydrophobic character of bamboo and linen treated fabric. Thus, g-C₃N₄ nanomaterials can be used as green coat to improve the properties of bamboo and linen fabrics. [ABSTRACT FROM AUTHOR]
