Preparation of BiOI/ZnO/chitosan composites and its application in linen fabric
In order to prepare multifunctional linen fabric,zinc oxide/chitosan composite materials were synthesized by chemical precipitation method with zinc acetate dihydrate as zinc source and chitosan as base.Bismuth oxyiodide/zinc oxide/chitosan(BiOI/ZnO/CS)composite materials was prepared via solvothermal method,Fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD),UV visible spectrophotometer(UV-vis)and scanning electron microscopy(SEM)were used to characterize the groups,crystal structure,photochemical properties and morphology of BiOI/ZnO/CS.Finally,the composite was loaded onto the linen fabric,X-ray diffraction(XRD)was used to characterize the linen fabric before and after finishing.The bacteriostatic and UV resistant properties of linen fabrics were tested.The results show that the BiOI/ZnO/CS has strong absorption of ultraviolet light and has been successfully loaded on linen fabric.After finishing,the antibacterial rate against S.aureus and E.coli reached 100%and the ultraviolet protection factor(UPF)value was 144.72.It has excellent antibacterial and ultraviolet resistance properties,which is of great significance to widen the application field of linen fabric.
