Title:
METHOD FOR PREPARING HYDROGEL DRESSING
Document Type and Number:
WIPO Patent Application WO/2019/100197
Kind Code:
A1
Abstract:
A method for preparing a hydrogel dressing, which relates to the technical field of polymer materials, comprising: mixing 1-8 parts by mass of an aqueous solution of silk fibroin and 3-6 parts by mass of an aqueous solution of polyurethane; adding 1-5 parts by mass of an aqueous solution of polyvinyl alcohol; reacting at a stirring rate of 500-700 for 20-30 minutes to obtain a composite aqueous solution, the mass fractions of the aqueous solution of silk fibroin, the aqueous solution of polyurethane, and the aqueous solution of polyvinyl alcohol respectively being: 1-10%, 20-40%, and 8-12.5%; mixing a phase-change energy storage microcapsule with the composite aqueous solution according to a mass ratio of 1:10-50; pouring the same into a mold for curing to obtain a hydrogel dressing. The method is simple and is suitable for large-scale use.
