A collagen/nano-TiO2/graphene composite fiber. The composite fiber is prepared by means of an electrospinning technology. The composite fiber comprises the following fibers in parts by weight: 40-50 parts by weight of collagen fiber; 20-30 parts by weight of nano-TiO2 fiber; and 25-35 parts by weight of graphene fiber. After collagen fiber, nano-TiO2 fiber, and graphene fiber are composited, different shapes and effects can be produced by means of different properties of the components.
