NOVELTY - Preparation of titania-based graphene/lanthanum ion carbon fiber comprises dissolving 0.0007-0.0049 g/mL graphene and 0.08 g/mL polyacrylonitrile in dimethylformamide to obtain graphene/polyacrylonitrile dimethylformamide mixture; and adding 0.0069 g/mL lanthanum nitrate to glacial acetic acid and tetra-n-butyl titanate mixed solution at volume ratio of 4:5, slowly adding into graphene/polyacrylonitrile dimethylformamide mixture at volume ratio of 50:9 while stirring, vacuum stirring to obtain spinning solution, electrospinning, drawing, pre-oxidizing, and calcining. USE - Method for preparation of titania-based graphene/lanthanum ion carbon fiber (claimed). ADVANTAGE - The method has high strength, simple production equipment, simple operation, and good antibacterial effect.
