Abstract

The invention discloses an ascidean cellulose nano crystal / polymer hydrogel and a preparation method thereof and an application thereof. The ascidean cellulose is prepared to an ascidean cellulose nano crystal aqueous suspension, a hydrophilic polymer monomer and an initiator are added into the ascidean cellulose nano crystal aqueous suspension, the materials are uniformly mixed, and a mixture is subjected to a crosslinking reaction under certain condition to obtain the ascidean cellulose nano crystal / polymer hydrogel. The method can regulate and control the usage amount of the initiator to control the crosslinking density, aperture size, swellability and mechanical strength of the hydrogel, the method is simple and convenient, cost is low, the prepared ascidean cellulose nano crystal / polymer hydrogel has the advantages of large tensile strength and no toxicity, and has good application prospect on the fields of papermaking, building, food, electronic products, and medical science.

Description

technical field

[0001] The invention relates to a sea squirt cellulose nanocrystal / polymer hydrogel and a preparation method and application thereof, belonging to the fields of chemical engineering and polymer materials. Background technique

[0002] Hydrogel is a type of soft material with a three-dimensional network structure that contains a large amount of water and is formed by cross-linked polymer chains interacting through covalent or non-covalent bonds. It can swell in water but not dissolve. Hydrogels are porous, good biocompatibility, and responsive to external stimuli, and are widely used in hygiene products, agriculture, and biomedicine. However, the synthesized hydrogels usually have poor mechanical properties, which seriously hinders their practical application. With the rapid development of composite materials, the preparation method of the cross-linked network nanocomposite hydrogel can effectively improve the mechanical properties of the gel through the inte...
