Preparing method for intelligent hydrogel fibers with double responses to temperature

The invention relates to a preparing method for intelligent hydrogel fibers with double responses to temperature. The preparing method comprises the steps that OEGMA and MEO2MA are mixed, photoinitiator is added, the mixture is stirred in the mode of being away from light, and in-situ free radical polymerization is carried out on the mixture to obtain POM; distilled water is added to the POM, PEGDA is added, and the mixture is stirred to obtain a mixed water solution; clay Laponite XLS is added into the obtained mixed water solution, photoinitiator is added, the mixture is stirred in the mode of being away from the light and stands, and bubbles are removed, so that a spinning solution is obtained; the spinning solution is introduced into a water bath, an ultraviolet-light point light source is arranged, and free radical polymerization is carried out to obtain hydrogel nascent fibers; the nascent fibers are drafted to obtain the hydrogel fibers. According to the obtained hydrogel fibers, the hydrogel fibers can be prepared continuously, the structural stability of the fibers is improved by means of a semi-interpenetrating network, the multiple responses of the fibers to the environment temperature can be achieved, and the preparing method has great significance in application and development of hydrogel materials and processing of the hydrogel materials at the later stage.
