Abstract

The present invention relates to the technical field of methods for preparing eutectic gels, and specifically discloses a method for rapidly initiating the polymerization of eutectic solvents to prepare eutectic gels, which specifically includes the following steps: Step 1, first, using industrial xylan, or cellulose, or glucomannan, or arabinoglucose, or mannan as raw materials, dialdehyde xylan (DAX) is prepared by the periodate oxidation method as follows: 20.0 g of industrial xylan is added to 800 mL of deionized water respectively, stirred until evenly dispersed to form a suspension, then 50.0 g of NaIO<subgt;4< / subgt; is weighed and added to the above suspension, and then stirred and reacted under dark at room temperature for different times. After the reaction is completed, 12 mL of ethylene glycol is slowly added to the reaction system to terminate the reaction; by using the dialdehyde xylan (DAX) solution to stabilize the LM nanodroplets, and using the DAX / LM dispersion to rapidly initiate the polymerization reaction of ChCl / AM in one step to prepare the DLPD eutectic gel, and no free radical initiator and crosslinking agent are required during the preparation process.
