As a semiconductor material, nano TiO2 has important application value in various professional fields. Single nano TiO2 has low light utilization and poor degradability. In order to improve the sustainability of material development, enhance the application value and performance of materials, this article combined polylactic acid (PLA) with nano TiO2 to form a composite material, and studied its preparation, characterization, and degradation behavior. This article first analyzed the characteristics of nano TiO2 and polylactic acid materials, then prepared and modified nano TiO2, and finally combined it with different mass ratios of polylactic acid to form composite material samples. To verify the material performance, this article conducted experiments from two aspects: characterization of crystallization performance and analysis of degradability. The results showed that the higher the PLA mass ratio, the more ideal the degradability of the composite material. Compared to the material with a PLA mass ratio of 0%, the degradability of the material sample with a PLA mass ratio of 3% ultimately increased by 0.12%. The conclusion indicates that the polylactic acid nano TiO2 composite material has excellent degradability, which helps to improve the environmental friendliness and application range of the material.
