| titleOfInvention | Preparation method of automatic continuous expansion-contraction porous hydrogel spheres |
| abstract | The invention provides a preparation method of a porous hydrogel sphere capable of automatically and continuously expanding and contracting, which comprises the steps of polymerizing and crosslinking an acryloyl-beta-cyclodextrin monomer and an N-isopropylacrylamide monomer to obtain the porous hydrogel sphere, soaking the porous hydrogel sphere in an 8-anilino-1-naphthalenesulfonic acid aqueous solution, and keeping the temperature of the aqueous solution constant at a determined temperature value within the range of 'the low critical solution temperature of the porous hydrogel sphere' and 'the low critical solution temperature when the beta-cyclodextrin in the porous hydrogel sphere is saturated in inclusion of 8-anilino-1-naphthalenesulfonic acid molecules', wherein the porous hydrogel sphere in the aqueous solution can automatically and continuously expand and contract. The temperature-responsive porous hydrogel solid capable of automatically and continuously expanding-contracting at a fixed temperature is prepared for the first time, the preparation method is simple, special equipment is not needed, the whole reaction process is simple and easy to control, the cost is low, and the popularization is easy. |
