摘要（英）：

The invention discloses a method for constructing a self-repairing nano-composite hydrogel based on a Janus nano-hybrid material prepared by cellulose nanocrystalline surface modification, and realizes preparation of polyacrylic acid-based self-repairing nano-composite hydrogel from a cellulose nanocrystalline-based Janus nano-hybrid material. The method includes: hydrolyzing microcrystalline cellulose with concentrated sulfuric acid to prepare CNCs; adding an initiator to polymerize the cellulose nanocrystalline and polylysine to prepare a cellulose nanocrystalline-based compound; and furtherperforming modification to prepare the cellulose nanocrystalline-based Janus nano-hybrid material successfully, and adopting the product as an additive to successfully prepare the self-repairing nano-composite hydrogel in which the cellulose nanocrystalline-based Janus nano-hybrid material participates.
