Description

technical field

[0001] The invention belongs to the technical field of polylactic acid nanocomposite materials, and in particular relates to a high-performance polylactic acid nanocomposite material and a preparation method thereof. Background technique

[0002] As the most abundant biomass resource on the earth, natural cellulose is a biological resource widely distributed in nature, and exists in various organisms such as plants and some other carriers. Cellulose nanocrystal is a nanoscale material extracted from natural fibers, because it has the excellent characteristics of both nanomaterials and cellulose, such as high mechanical strength, amphiphilicity, optical activity, and various surface modifications. It has received extensive attention from researchers in different fields.

[0003] With the continuous improvement of people's quality of life, people pay more and more attention to the protection of the environment. Because the "white pollution" caused by traditio...
