Abstract: In order to prepare mulberry fiber-based hydrogel, mulberry fiber/sodium alginate double network hydrogel was prepared by the blending method, with mulberry fiber as its skeleton structure, and sodium alginate as its functional component of flexible layers. The paper analyses the morphology as well as the rheological property of hydrogel, and optimizes the preparation technology of mulberry fiber/sodium alginate hydrogel, providing a reference for the preparation of cellulose-based hydrogel.
