Abstract: A graphene quantum dot/polymer antibacterial and antiviral composite fiber and a preparation method therefor are provided. The graphene quantum dot/polymer antibacterial and antiviral composite fiber is prepared by melt spinning, solving problems that graphene quantum dots are easy to agglomerate and difficult to be effectively oriented. In addition, the composite fiber has excellent antibacterial and antibacterial properties, as well as good mechanical properties, environmental friendliness, a silky and smooth feel, a plump and glutinous cashmere, fluffy, good rebound, comfortable touch, and good wearing performance. Furthermore, according to different addition amounts of the graphene quantum dots, the graphene quantum dots have various colors, such as original white, light tea color or light coffee color, which breaks through an inherent color limitation of traditional graphene modified fibers in black and gray.
