Based on the principles of gel preparation via freeze-thaw method and research progress in hydrogel synthesis, this study explores the effects of different pressure parameters systematically from the perspective of pressure regulation. Pressure magnitude, pressure compression and decompression rate, and number of cyclic loading were investigated during the gelation process of polymer solutions. By using the alternate compression-decompression (ACD) method, efficient and rapid synthesis of a series of hydrogels with excellent mechanical strength is enabled. These hydrogels have potential applications in diverse fields, including biomedicine, environmental protection, and electronic devices. As an innovative approach, the ACD method not only expands the preparation strategies for hydrogels significantly but also enhances the application potential of hydrogels in the field of soft matter science, providing new insights and directions for further development in this field.
