The invention provides a preparation method of a titanium dioxide/polylactic acid nanocomposite, and belongs to the technical field of composite materials. The preparation method comprises the step of: based on lactic acid and tetrabutyl titanate as the raw materials and stannous octoate as the catalyst, compositing to obtain the titanium dioxide/polylactic acid (TiO2/PLA) nanocomposite at one time under the nitrogen environment. According to the nanocomposite, polylactic acid is the nanocrystalline structure material which grows along the specified direction, TiO2 of nanometer size is uniformly dispersed in the substrate of PLA, and TiO2 and PLA are combined by a chemical bond shown as Ti-O-C, so that the nanocomposite can fully perform original characteristics of organic-inorganic materials and effectively improve the comprehensive performances at the same time; and furthermore, the preparation method has the characteristics of being simple in technology, short in process, lower in cost and high in yield.
