Title:
ANISOTROPIC CELLULOSE-BASED HYDROGEL PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/174502
Kind Code:
A1
Abstract:
An anisotropic cellulose-based hydrogel preparation method, comprising the following steps: ammoniating dialdehyde cellulose obtained after oxidation of sodium periodate; performing a Schiff reaction between ammoniated cellulose and dopamine to obtain a cellulose-dopamine nanosheet; depositing Fe3O4 nanoparticles on the surface of the cellulose-dopamine nanosheet by using a deposition method to obtain a magnetic cellulose-dopamine nanosheet; and forming, by means of a simple polymerization method, a hydrogel by the cellulose in which the nanoparticles are deposited. Cellulose widely existing in biomass is used as a raw material, resulting in low costs; the whole experiment process is mild in reaction conditions and less in pollution, the obtained cellulose-based hydrogel has typical anisotropy and magnetism, an application path of cellulose is widened, and extremely high potential value is achieved.
