Extremely compressible hydrogels are fabricated in one pot via sulfonic‐acid‐modified graphitic carbon nitride (g‐CN‐AHPA) as a visible light photoinitiator and reinforcer. The hydrogels show unusual compressibility upon applied stress up to 12 MPa, presenting temporary physical deformation, and remain undamaged after stress removal despite their high water content (90 wt%). Cyclic compressibility proves the fatigue resistance of the covalently and electrostatically reinforced system that possesses tissue adhesive properties, shock resistance, cut resistance, and little to no toxicity.

通过掺入改性石墨碳氮化物极易压缩的水凝胶

极易压缩的水凝胶通过磺酸改性的石墨氮化碳（g-CN-AHPA）作为可见光光引发剂和增强剂在一个罐中制成。水凝胶在施加高达12 MPa的应力时显示出异常的可压缩性，表现出暂时的物理变形，尽管水含量高（90 wt％），但在应力消除后仍保持不变。循环压缩性证明了共价和静电增强系统的耐疲劳性，该系统具有组织粘合特性，耐冲击性，耐切割性，并且几乎没有毒性。
