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.
通过磺化改性石墨相氮化碳（g-CN-AHPA）作为可见光光引发剂和增强剂，一锅法制备了超可压缩水凝胶。该水凝胶在高达 12 MPa 的外加应力下表现出异常的可压缩性，呈现出暂时的物理变形，在去除应力后仍保持完好无损，尽管其含水量高达 90 wt%。循环压缩性证明了共价和静电增强体系的耐疲劳性，该体系具有组织胶粘性、抗冲击性、抗切割性，且毒性很小或几乎没有。
