Lignin is the second most abundant polymer resource in nature, composed of natural aromatic polymers. Recently, as interest in the virtuous cycle of carbon resources increases, interest in the application of lignin is also increasing. However, the complexity and low polymer processability of lignin make it significantly less accessible for practical applications. Therefore, the purpose of this study is to prepare a lignin-containing nanocellulose hydrogel by adding lignin to a regenerated nanocellulose hydrogel prepared using an eco-friendly solvent system. This process complements the structural instability of the lignin and improves the mechanical properties of the hydrogel Ultimately, the addition of lignin could dramatically increase the dye removal capacity of nanocellulose hydrogels. These results suggest that nanocellulose hydrogels containing lignin can be used as a potential water restoration material. |
