Title:
NANOCELLULOSE-BASED MULTIFUNCTIONAL ELECTRICALLY-CONDUCTIVE COMPOSITE HYDROGEL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/031904
Kind Code:
A1
Abstract:
The present invention pertains to the technical field of nanocellulose materials, and provides a nanocellulose-based multifunctional electrically-conductive composite hydrogel and a preparation method therefor. Specifically, the preparation method comprises: adding tannic acid to a cellulose nanocrystal suspension to obtain a tannic acid surface-modified cellulose nanocrystal; combining single-layer MXene and the tannic acid surface-modified cellulose nanocrystal to form a composite; and taking acrylamide as a polymer gel network, adding N,N'-methylenebisacrylamide as a cross-linking agent, ammonium persulfate as an initiator, and N,N,N',N'-tetramethylethylenediamine as an accelerator, and preparing the nanocellulose-based multifunctional electrically-conductive composite hydrogel by means of thermal initiation polymerization. The preparation method of the present invention is based on the compounding of nanocellulose. The nanocellulose-based multifunctional electrically-conductive composite hydrogel is prepared by means of a simple and cheap method, and has excellent characteristics including high mechanical strength, good fatigue resistance, and good biocompatibility.
