In order to enable undergraduate students majoring in chemistry and related fields to understand the basic characteristics of hydrogel materials and their applications in macroscopic non-equilibrium supramolecular self-assembly, we have introduced a comprehensive research-oriented experiment titled "Macroscopic Non-equilibrium Supramolecular Self-Assembly Experiment". This experiment mainly includes the preparation method of polyelectrolyte hydrogels based on homogeneous free radical polymerization, the construction method of macroscopic non-equilibrium supramolecular self-assembly system based on urea-urease timing reaction, characterization of assembly performance, and exploration of the mechanisms of non-equilibrium assembly and disassembly. Through the practice of this experiment, students can deepen their understanding of supramolecular interactions, master the preparation and characterization methods of relevant polymer hydrogels, as well as consolidate the use of some commonly used instruments. By combining teaching and practice, we establish a bridge between teaching and scientific research to broaden students' scientific perspectives, stimulate their research interests, and cultivate students' innovative abilities and scientific thinking.
