Abstract: Based on the mechanism of gelation of polymeric hydrogels via freezing-thawing method and the related results, the effects of different pressure parameters (pressure magnitude, pressure compression and decompression rate, and number of cyclic loading) were investigated during the gelation process of polymer solutions from the perspective of pressure regulation. By using the alternate compression-decompression (ACD) method, a series of hydrogels with excellent mechanical strength can be efficiently and rapidly synthesized. Their potential applications cover multiple fields such as biomedicine, environmental protection, and electronic devices. The alternate compression-decompression method not only greatly broadens the preparation strategies of hydrogels, but also significantly enhances the application potential of hydrogels in the field of soft matter science, providing new ideas and directions for the further development of this field.
