Preparation method of metal-doped titanium dioxide nanowire/segmented copolymer composite nanoparticles

The invention provides metal-doped titanium dioxide nanowire/segmented copolymer composite nanoparticles and a preparation method thereof, and belongs to the technical field of composite materials. Metal doping is performed on the titanium dioxide nanowires, so that the physicochemical properties of the titanium dioxide nanowires are improved, and the compounding capacity of the titanium dioxide nanowires and the block copolymer is enhanced. According to the preparation method, an ultraviolet polymerization induced self-assembly method is adopted, under the condition of ultraviolet light, a poly (4-vinylpyridine) macromolecular chain transfer agent and a styrene monomer are co-assembled with metal-doped titanium dioxide nanowires in the in-situ polymerization process, and therefore the novel titanium dioxide nanowire/segmented copolymer composite nanoparticles are prepared. The method disclosed by the invention has the advantages of simple experimental operation, high yield, adjustable nano material size and
