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 show unusual compressibility upon applied stress up to 12 MPa, presenting temporary physical deformation, remain undamaged after removal despite their high water content (90 wt%). Cyclic proves the fatigue resistance of covalently electrostatically reinforced system that possesses tissue adhesive properties, shock resistance, cut little no toxicity.
