23 Jul Preparation method of high strength hydrogel with simulated insect cuticle structure
Abstract
The invention belongs to the field of biomass materials, and relates to a preparation method of a high strength hydrogel with a simulated insect cuticle structure. The preparation method comprises following steps: (1) subjecting chitin to a partial deacetylation treatment; (2) diluting the product obtained in the step (1) by an acetic acid solution, and then grinding the product; (3) diluting theproduct obtained in the step (2) by distilled water, carrying out an ultrasonic treatment, filtering the solution in vacuum, and carrying out film forming; (4) fully impregnating the product obtainedin the step (3) in a gelatin solution; and (5) impregnating the product obtained in the step (4) into a quinone crosslinking reaction solution, and making the product carry out quinone crosslinking reactions at a room temperature to obtain partially de-acetylated chitin nano fiber/gelatin composite gel. The operation of the method is simple and rapid; and moreover, the prepared composite hydrogelhas excellent mechanical properties and has a great application value in fields such as artificial skin, biosensors, soft tissue engineering materials, and the like.
