Herein, the report on a new class of self‐healing and pH/temperature responsive mixed solvent (ethanol and water) gels shows unusual mechanical properties to resist slicing, sustain high compression, and withstand stretching as evidenced by the cutting breaking stress, the fracture compressive stress, and the stretching ratio of one of the gels as obtained can reach or exceed 26.4 MPa, 9.2 MPa, and ≈5 times, respectively. The gels are designed by introducing dynamic covalent bond, acylhydrazone, which is believed to combine the merits of conventional chemical bonds and those of supramolecular interactions. Specifically, a hydrazide‐modified calix[4]arene derivative and linear benzaldehyde‐terminated poly(ethylene glycol)s are synthesized and used as reactive components to build gel networks. Interestingly, acid‐degradable hydrogel can be obtained via natural drying of the mixed solvent gel first and then swelling in pure water.

基于Calix [4] arene的动态共价凝胶：鲁棒性，响应性和自我修复的结合

此处，关于新型自愈和pH /温度响应混合溶剂（乙醇和水）凝胶的报告显示了非凡的机械性能，可抵抗切片，维持高压缩力并承受拉伸，如切割断裂应力，断裂所证明的那样。所获得的一种凝胶的压缩应力和拉伸比分别可以达到或超过26.4 MPa，9.2 MPa和≈5倍。通过引入动态共价键酰基hydr来设计凝胶，据信它结合了常规化学键和超分子相互作用的优点。具体来说，可以合成酰肼改性的杯[4]芳烃衍生物和线性苯甲醛封端的聚乙二醇，并将其用作反应性组分以建立凝胶网络。有趣的是，
