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.
